I have a repository that runs some Github Actions overnight, and now these tests are failing in the mamba-org/setup-micromamba@v2 stage while trying to install some dependencies with pip:
Installing pip packages: sphinx-click, sphinxcontrib-autoyaml, git+https://github.com/dask/dask-mpi.git, --editable=..

critical libmamba pip failed to install packages
The last successful run was Sunday night, and then it started to fail. As far as I can tell, pyyaml is in the environment that mamba is trying to create, but I've tried:
pyyaml to the environment filepip install pyyaml before running micromamba (it was already installed with the system python)pipI don't see what else changed between those two runs... has anyone else seen something like this? Did you find a solution?
I'd have to look deeper to know exactly what's going on, but often the conda/mamba + pip installs are quite brittle and more things are on conda-forge these days. It might be worth seeing if you can install everything via conda-forge.
Moving from pip to conda-forge seems to have done the trick -- thanks for the suggestion! I'm getting a sphinx build error in the build-docs test, but at least the environment is being created successfully :)
