Conda recipes

Create a new recipe for a pure Python package on PyPI

1. Install conda-build, anaconda and grayskull to your base Conda env:

   conda install conda-build anaconda-client grayskull
   

   Note: I personally prefer using Boa and a dedicated Conda env:

   conda create --name conda-build
   conda install -c conda-forge conda-build boa anaconda-client grayskull
   

2. Use the grayskull online interface to create a new recipe file and fine-tune it. Alternatively, you can also use the command-line interface for that purpose:

   grayskull pypi <package>
   

   Do not forget to review the produced recipe before proceeding!

3. Build the recipe:

   conda build <package>
   

   You might have to add extra channels to this command to correctly resolve dependencies. Example:

   conda build -c conda-forge <package>
   

   You can also use Mamba as your env solver for improved build performance (install Boa first):

   conda mambabuild -c conda-forge <package>
   

4. Upload to Anaconda Cloud

   anaconda upload <path_to_created_package>
   

   Want to upload to an organisation you're a member of? Use the --user flag:

   anaconda upload --user <your_username> <path_to_created_package>
   

Troubleshooting: Upload fails silently

While uploading, check the error code carefully. If the upload step finishes and returns a code different from 0 (echo $? will show the exit code), something went wrong and the upload did not succeed. This is a long-discussed issue (e.g. anaconda/anaconda-client#501) and this silent failure can have several reasons.

I had trouble using anaconda-client 1.7.2 with Python 3.9.4. Using Python 3.7 fixed the issue.

Troubleshooting: ModuleNotFoundError: No module named 'poetry'

If this happens, try and add poetry to your recipe's requirements.host section.
