Conda build fails with `Aborting implicit building of eggs.` message

Question

I am trying to build a new conda package based on an old one. The repo and code is available for Theme Material Darcula. Theme-material-darcula Jupyter labextension builds and install perfectly fine on my system. But the conda build . command fails for me on Aborting implicit building of eggs. Use pip install. to install from source.

The traceback is here:

What am I doing wrong?

Answer 1

I’ll answer my own question.

I’m building the package the wrong way. The package is supposed to be built using python setuptools via:

python3 setup.py sdist

which will create tarball file dist directory.

This file is supposed to be published to PyPI. A bash script will make the job a whole lot easier (do make sure to create an account on TestPyPI and PyPI):

# Adapted from https://github.com/jupyter-lsp/jupyterlab-lsp/blob/master/scripts/publish_pypi.sh

rm dist/*
python3 setup.py sdist
twine upload dist/* -r testpypi
echo "Published to testpypi"
while true; do
    read -p "Do you wish to publish to pypi?" yn
    case $yn in
        [Yy]* ) twine upload dist/*; break;;
        [Nn]* ) exit;;
        * ) echo "Please answer yes or no.";;
    esac
done

The script will first create tarball file and then first publish it to TestPyPI, if all looks fine, continue with publishing on PyPI.

Publishing to Conda

The same python package can be published to Conda via anaconda-client:

conda activate <enironment-name>
conda install anaconda-client
anaconda login

Then upload it:

anaconda upload dist/*
