Possible to export pip-packages?

[JohannesWiesner]

I am using setup-micromamba@v1 to create environments and would like to export them as text files, either with micromamba env export --name ... > file.yml or conda list --explicit > file.txt. However, I noticed that pip-packages are not included in the exported text files. Is this behavior normal?

Here's an example repo where I use the workflow to create an environment based on the input file environment.yml, export it to text files and then push it back to the repo (the two files with _solved as suffixes).

See mamba-org/mamba#2008

For now, you could do something like this:

- name: setup micromamba and solve environment
  uses: mamba-org/setup-micromamba@v1
  with:
    environment-file: environment.yml
    environment-name: ${{ runner.os }}
- name: export environment created with micromamba using conda
  run: |
    conda env export -p "${MAMBA_ROOT_PREFIX}/envs/${{ runner.os }}" > ./environments/${{ runner.os }}_solved_with_pip.yml

Btw conda list --explicit can be replaced by micromamba env export --explicit.

Thanks! Just as a sanity check:

1.) If one wants to output a .yml file, -p "${MAMBA_ROOT_PREFIX}/envs/name_of_my_environment" does the trick. Right now, this only works in combination with conda env export, not micromamba env export.

2.) However, if one wants to output a spec file with the exact package URLs, neither conda list --explicit nor micromamba env export --explicit will include pip-packages which is probably out of scope of this repo and which is addressed in this issue

Yes, seems right 👍🏻
