ClobberWarning with a simple conda build

Question

I am trying to build a simple package (only python code) and I get this warning:

ClobberWarning: This transaction has incompatible packages due to a shared path.
  packages: conda-forge/noarch::tomli-2.0.1-pyhd8ed1ab_0, conda-forge/osx-arm64::mypy-1.2.0-py311he2be06e_0
  path: 'lib/python3.11/site-packages/tomli/__pycache__/__init__.cpython-311.pyc'

I followed the suggested practice of installing packages from the same channel, but yet I got this issue.

How can I solve it?

Answer 1

This has now been patched. Would need to update to latest build of v1.7.1 (or higher) to get the fix.

Original answer

Looks like a bug in the Conda Forge mypy feedstock, i.e., mypy shouldn't be capturing files from the site-packages/tomli directory. There is an Issue filed for this on the feedstock.

Since the version of tomli is very likely the same as what mypy=1.2.0 was built with, it is likely safe to ignore. Maybe consider running some of the tests just to get peace of mind. Otherwise, would need to wait for feedstock to be updated.
