OS-agnostic, system-level binary package manager and ecosystem


Conda Logo

CI Tests (GitHub Actions) Codecov Status latest release version

Conda is a cross-platform, language-agnostic binary package manager. It is the package manager used by Anaconda installations, but it may be used for other systems as well. Conda makes environments first-class citizens, making it easy to create independent environments even for C libraries. Conda is written entirely in Python, and is BSD licensed open source.

Conda is enhanced by organizations, tools, and repositories created and managed by the amazing members of the conda community. Some of them can be found here.


Conda is a part of the Anaconda Distribution. Use Miniconda to bootstrap a minimal installation that only includes conda and its dependencies.

Getting Started

If you install Anaconda, you will already have hundreds of packages installed. You can see what packages are installed by running

$ conda list

to see all the packages that are available, use

$ conda search

and to install a package, use

$ conda install <package-name>

The real power of conda comes from its ability to manage environments. In conda, an environment can be thought of as a completely separate installation. Conda installs packages into environments efficiently using hard links by default when it is possible, so environments are space efficient, and take seconds to create.

The default environment, which conda itself is installed into is called base. To create another environment, use the conda create command. For instance, to create an environment with the IPython notebook and NumPy 1.6, which is older than the version that comes with Anaconda by default, you would run

$ conda create -n numpy16 ipython-notebook numpy=1.6

This creates an environment called numpy16 with the latest version of the IPython notebook, NumPy 1.6, and their dependencies.

We can now activate this environment, use

# On Linux and Mac OS X
$ source activate numpy16

# On Windows
> activate numpy16

This puts the bin directory of the numpy16 environment in the front of the PATH, and sets it as the default environment for all subsequent conda commands.

To go back to the base environment, use

# On Linux and Mac OS X
$ source deactivate

# On Windows
> deactivate

Building Your Own Packages

You can easily build your own packages for conda, and upload them to anaconda.org, a free service for hosting packages for conda, as well as other package managers. To build a package, create a recipe. Package building documentation is available here. See https://github.com/AnacondaRecipes for the recipes that make up the Anaconda Distribution and defaults channel. Conda-forge and Bioconda are community-driven conda-based distributions.

To upload to anaconda.org, create an account. Then, install the anaconda-client and login

$ conda install anaconda-client
$ anaconda login

Then, after you build your recipe

$ conda build <recipe-dir>

you will be prompted to upload to anaconda.org.

To add your anaconda.org channel, or the channel of others to conda so that conda install will find and install their packages, run

$ conda config --add channels https://conda.anaconda.org/username

(replacing username with the user name of the person whose channel you want to add).

Getting Help

The documentation for conda is at https://conda.io/en/latest/. You can subscribe to the conda mailing list. The source code and issue tracker for conda are on GitHub.


Contributions to conda are welcome. See the contributing documentation for instructions on setting up a development environment.

    Current Behavior

    conda operations appear to be particularly slow, this seems to have got worse as the versions have progressed.

    Steps to Reproduce

    time conda install -c simplistix picky-conda=2.0.2

    The above currently takes 30-40s into an existing environment.

    Expected Behavior

    Hopefully done and dusted within a second or two.

    NotWritableError: The current user does not have write permissions to a required path.

    Conda is seriously confused about permissions. Right after I installed Anaconda from Anaconda3-5.1.0-Linux-x86_64.sh into my home (/home/marek/anaconda3) and added

    . /home/marek/anaconda3/etc/profile.d/conda.sh

    into my ~/.zshrc and started new shell, I tried to create new environment:

    % conda create --name condatest python=3
    Solving environment: failed
    NotWritableError: The current user does not have write permissions to a required path.
      path: /home/marek/.conda/pkgs/urls.txt
      uid: 1009
      gid: 1009
    If you feel that permissions on this path are set incorrectly, you can manually
    change them by executing
      $ sudo chown 1009:1009 /home/marek/.conda/pkgs/urls.txt
    In general, it's not advisable to use 'sudo conda'.
    • My user and group ids are 1009.
    • ~/.conda directory didn't exist before I run the command above
    • ~/.conda directory DID exist after I run the command above, though it was empty
    • % touch ~/.conda/foo works

    This happens on latest ArchLinux, latest Ubuntu (bionic) and with both bash and zsh as shell...

    Recent conda changes breaking Travis

    Not 100% sure that this is a conda issue, but it looks like changes in .27 are breaking Travis builds that use extension modules.

    In particular, the compiler is identified as

    compiler: x86_64-conda_cos6-linux-gnu-gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -fwrapv -O2 -Wall -Wstrict-prototypes -march=nocona -mtune=haswell -ftree-vectorize -fPIC -fstack-protector-strong -fno-plt -O2 -pipe -march=nocona -mtune=haswell -ftree-vectorize -fPIC -fstack-protector-strong -fno-plt -O2 -pipe -fPIC

    Not sure why conda would be in the compiler.

  • Add generic support for bourne- and c-based shells

    Add generic support for bourne- and c-based shells

    With these changes conda's activate/deactivate now support bash/zsh/tcsh/csh.

    The scripts assume that activate*, deactivate*, and conda* can be found on the user's $PATH as opposed to detecting the $_SCRIPT_LOCATION as was done previously. This change is necessary to support tcsh/csh where the script location cannot be reliably detected when sourced.


    source activate [ENVNAME]
    source deactivate

    tcsh/csh (since the which command doesn't search the user $PATH in tcsh/csh):

    source \`which activate\` [ENVNAME]
    source \`which deactivate\`

    The old activate script has effectively been renamed as activate.sh. Likewise with the old deactivate script. They contain the same content but has been slightly edited to match the look and feel of the *.csh scripts that have been introduced.

    It may also make sense to encourage users to create aliases when they install Conda.


    alias activate="source activate"
    alias deactivate="source deactivate"


    alias activate    "source \`which \activate\`"
    alias deactivate  "source \`which \deactivate\`"

    What happened?

    With channel_priority: strict in my .condarc, I get

    UnsatisfiableError: The following specifications were found to be incompatible with each other

    when creating a new environment, but, looking at the conflicts, I see none. No such problem arises with an empty .condarc, and I experience no environment problems.

    You can see that python=3.9 and openssl=3.0.3 would satisfy the package requirements and that glibc 2.17, installed on my system, does in fact satisfy the requirements.

    There is already a note about strict channel priority, but ultimately, this output is unhelpful for debugging.

  • Move all `conda-content-trust` logic into `conda-content-trust`

    Move all `conda-content-trust` logic into `conda-content-trust`


    In an effort to speed up package signature verification we move the verification process to occur after solving. This way only the packages included in the transaction are validated (tens of packages, not thousands).

    A secondary goal was to move even more of the signature verification logic into conda-content-trust itself. This is in preparation for making this a conda plugin once the framework is available (#11435). With this change, conda knows/cares even less about what and how signature verification happens.

    Resolves #11154 See conda/conda-content-trust#29

    Minor documentation update - `pip` dependency


    Documentation update. Includes an explicit declaration of pip as a dependency when installing a pip-installed dependency.

    Resolves warning:

    Warning: you have pip-installed dependencies in your environment file, but you do not list pip itself as one of your conda dependencies. Conda may not use the correct pip to install your packages, and they may end up in the wrong place. Please add an explicit pip dependency. I'm adding one for you, but still nagging you.

  • 4.12.0(Mar 8, 2022)


    • Add support for libmamba integrations. (#11193)

      This is a new experimental and opt-in feature that allows use of the new conda-libmamba-solver for an improved user experience, based on the libmamba community project – the library version of the mamba package manager.

      After updating your conda version to 4.12.0, please follow these steps to try out the new libmamba solver integration:

      1. Install the separate conda-libmamba-solver package in your conda base environment:

        conda install -n base conda-libmamba-solver
      2. Try out the solver using the --experimental-solver=libmamba command line option.

        E.g. with a dry-run to install the scipy pacakge:

        conda create -n demo scipy --dry-run --experimental-solver=libmamba

        Or install in an activated conda environment:

        conda activate my-environment
        conda install scipy --experimental-solver=libmamba
    • Make sure that conda env update -f sets env vars from the referenced yaml file. (#10652)

    • Improve command line argument quoting, especially for conda run. (#11189)

    • Allow conda run to work in read-only environments. (#11215)

    • Support running conda with PyPy on Windows.
    • Add ability to add, append and prepend to sequence values when using the conda config subcommand.
    • Support Python 3.10 in version parser.
    • Add XDG_CONFIG_HOME to the conda search path following the XDG Base Directory Specification (XDGBDS).

    Bug fixes

    • Fix the PowerShell activator to not show an error when unsetting environment variables.
    • Remove superfluous eval statements in fish shell integration.
    • Indent the conda fish integration file using fish_indent.
    • Fix handling of environment variables containing equal signs (=).
    • Handle permission errors when listing all known prefixes.
    • Catch Unicode decoding errors when parsing conda-meta files.
    • Fix handling write errors when trying to create package cache or env directories.


    • Update path of conda repo in RHEL based systems to /etc/yum.repos.d/conda.repo.
    • Fix the advanced pip example to stop using the now invalid file: prefix.
    • Minor docs cleanup and adding Code of Conduct.

    • Expand the contributing documentation with a section about static code analysis and code linting.
    • Add developer guide section to the documentation, including a conda architecture overview.
    • Stop referring to updating anaconda when conda update fails with an error.


    • Build Docker images periodically on GitHub Actions for the continuous integration testing on Linux, storing them on GitHub Packages's registry for reduced latency and cost when using Docker Hub.

    • Simplify the Linux GitHub actions workflows by combining used shell scripts.

    • Add periodic GitHub Actions workflow to review old issues in the conda issue tracker and mark them as stale if no feedback is provided in a sensible amount of time, eventually closing them.

    • Add periodic GitHub Actions workflow to lock the comment threads of old issues and pull requests in the conda GitHub repository to surface regressions with new issues instead.

    • Refactor test suite to use more GitHub Actions runners in parallel, reducing total run time by 50%.

    • Switched the issue tracker to use forms with additional questions for bug reporters to help in ticket triage.

    • Add and automatically run pre-commit as part of the CI system to improve the code quality continuously and raise issues in contributed patches early on.

      The used code linters are: flake8, pylint and bandit.

      The Python code formatter black is used as well but is only enforced on changed code in a commit and not to the whole code base at once.

    • Automatically build the conda package upon the successful merge into the master branch and upload it to the conda-canary channel on anaconda.org.

      To try conda out simply run:

      conda install -c conda-canary/label/dev conda
    • Automate adding new issues to public GitHub project board to facilitate issue triage.

    • Update GitHub issue and pull request labels to be more consistent.

    • Start using rever for release management.

    • (preview) Enable one-click gitpod and GitHub Codespaces setup for Linux development.

    4.7.2 (2019-06-10)

    Behavior changes

    • unsatisfiability is determined in a slightly different way now. It no longer uses the SAT solver, but rather determines whether any specs have no candidates at all after running through get_reduced_index. This has been faster in benchmarks, but we welcome further data from your use cases about whether this was a good change. (#8741)
    • when using the --only-deps flag for the install command, conda now explicitly records those specs in your history. This primarily serves to reduce conda accidentally removing packages that you have actually requested. (#8766)


    • UnsatisfiableError messages are now grouped into categories and explained a bit better. (#8741)
    • --repodata-fn argument can be passed multiple times to have more fallback paths. repodata_fns conda config setting does the same thing, but saves you from needing to do it for every command invocation. (#8741)

    Bug fixes

    • fix channel flip-flopping that was happening when adding a channel other than earlier ones (#8741)
    • refactor flow control for multiple repodata files to not use exceptions (#8741)
    • force conda to use only old .tar.bz2 files if conda-build <3.18.3 is installed. Conda-build breaks when inspecting file contents, and this is fixed in conda-build 3.18.3 (#8741)
    • use --force when using rsync to improve behavior with folders that may exist in the destination somehow. (#8750)
    • handle EPERM errors when renaming, because MacOS lets you remove or create files, but not rename them. Thanks Apple. (#8755)
    • fix conda removing packages installed via install with --only-deps flag when either update or remove commands are run. See behavior changes above. (#8766)

    4.7.1 (2019-05-30)


    • Base initial solver specs map on explicitly requested specs (new and historic) (#8689)
    • Improve anonymization of automatic error reporting (#8715)
    • Add option to keep using .tar.bz2 files, in case new .conda isn't working for whatever reason (#8723)

    Bug fixes

    • fix parsing hyphenated PyPI specs (change hyphens in versions to .) (#8688)
    • fix PrefixRecord creation when file inputs are .conda files (#8689)
    • fix PrefixRecord creation for pip-installed packages (#8689)
    • fix progress bar stopping at 75% (no extract progress with new libarchive) (#8689)
    • preserve pre-4.7 download() interface in conda.exports (#8698)
    • virtual packages (such as cuda) are represented by leading double underscores by convention, to avoid confusion with existing single underscore packages that serve other purposes (#8738)

    Deprecations/Breaking Changes

    • The --prune flag no longer does anything. Pruning is implicitly the standard behavior now as a result of the initial solver specs coming from explicitly requested specs. Conda will remove packages that are not explicitly requested and are not required directly or indirectly by any explicitly installed package.

    Docs improvements

    • Document removal of the free channel from defaults (#8682)
    • Add reference to conda config --describe (#8712)
    • Add a tutorial for .condarc modification (#8737)
