Uploading and installing conda packages#

To work with conda packages, you must use the corresponding subdomain https://conda.anaconda.org. To install conda packages from the user travis, for example, use the repository URL https://conda.anaconda.org/travis.

Uploading conda packages#

This example shows how to build and upload a conda package to Anaconda.org using conda build.

Open a terminal (Anaconda Prompt for Windows users).
If necessary, install the anaconda-client and conda-build packages by running the following command:
```
conda install anaconda-client conda-build
```
Choose the repository for which you would like to build the package. In this example, we use a small public conda test package:
```
# Replace <PACKAGE_NAME> with the package name
git clone https://github.com/Anaconda-Platform/anaconda-client
cd anaconda-client/<PACKAGE_NAME>/conda/
```
In this directory, there are two required files, meta.yaml and build.sh.

macOS and Linux systems are Unix systems. Packages built for Unix systems require a build.sh file, packages built for Windows require a bld.bat file, and packages built for both Windows and Unix systems require both a build.sh file and a bld.bat file. All packages require a meta.yaml file.
To build the package, turn off automatic Client uploading and then run the conda build command:
```
conda config --set anaconda_upload no
conda build .
```
All packages built in this way are placed in a subdirectory of the Anaconda conda-bld directory.
Tip

You can check where the resulting file was placed by adding the --output option:
```
conda build . --output
```

Upload the test package to Anaconda.org by running the Anaconda upload command:

anaconda login

# Replace </PATH/TO/PACKAGE_NAME> with the correct file path and package name
# Packages can be uploaded with .tar.bz2 or .conda compression formats
anaconda upload </PATH/TO/PACKAGE_NAME>.tar.bz2
anaconda upload </PATH/TO/PACKAGE_NAME>.conda

For more information on the .conda format, see Using the .conda compression format.

Installing conda packages#

You can install conda packages from Anaconda.org by adding channels to your conda configuration.

Public channels#

Open a terminal (Anaconda Prompt for Windows users).
Because conda knows how to interact with Anaconda.org, specifying the channel sean, for example, translates to https://anaconda.org/sean:
```
conda config --add channels sean
```
You can now install public conda packages from Sean’s Anaconda.org account. Try installing the testci package at https://anaconda.org/sean/testci:
```
conda install testci
```

Private channels#

You can install a package from a private channel with a token and a Label:

# Replace <TOKEN> with the provided token
# Replace <CHANNEL> with a user channel
# Replace <LABEL_NAME> with the label name
# Replace <PACKAGE_NAME> with the name of the package you want to install
conda install -c https://conda.anaconda.org/t/<TOKEN>/<CHANNEL>/label/<LABEL_NAME> <PACKAGE_NAME>

Tokens are only required if the channel is private.

Finding help for uploading packages#

You can obtain a complete list of upload options, including:

Package channel.
Label.
Availability to other users.
Metadata.

To list the options, run the following in a terminal (Anaconda Prompt for Windows users):

anaconda upload -h
