I’m seeing a similar issue, with messages like the the one shown below. The part of the error message about pip is spurious, because I have learned from hard experience that one should NEVER use pip under any circumstances.

(py38) >conda-pack -n py38 Collecting packages… CondaPackError: Files managed by conda were found to have been deleted/overwritten in the following packages:

• python=‘3.8.5’

This is usually due to pip uninstalling or clobbering conda managed files, resulting in an inconsistent environment. Please check your environment for conda/pip conflicts using conda list, and fix the environment by ensuring only one version of each package is installed (conda preferred).

When I run conda list, I get the output shown below. As far as I can tell, there is only one version of each package. The list shows that two items came from pypi, but I don’t use pip, so I’m unclear as to how these could have gotten installed.

@Phillip-M-Feldman please try the --ignore-missing-files in your case. I’ve noticed this problem with the Python package as well. It’s a duplicate of #145 .

@AaronFaltesek that is, to be frank, way too many Pip packages. Conda-pack is intended to pack environments that were built almost exclusively with conda. In particular, pip packages with binary files have a high probability of failure. You too can try --ignore-missing-files but I would be very concerned that this just will not work for your environment.
