Conda-pack: CondaPackError: files managed by conda were

Question

So, I have a python project where all my tests run but then I do:

conda install -y conda-pack

which succeeds and when I run:

conda-pack

I get a lengthy complaint:

Collecting packages...

I see no issues in conda list and I can still run my tests. I see no issues with my environment. Ideas?

Answer 1

This should be related to this issue: https://github.com/conda/conda-pack/issues/198

The root cause is that the image is trying to use python3.10 and conda-pack parse it as python3.1.

They claimed to have fixed it in conda-pack 0.7.0 (release note) but I was using 0.7.0 and still see this problem.

One workaround is to specify another python version in a new env:

conda create -n new_env python=3.9 ${other_packages}
conda install conda-pack

conda-pack -n new_env ${your_other_options}
