Support installing Python release candidates #365

Open dstansby opened 1 month ago

dstansby commented 1 month ago

For testing purposes, it would be nice to be able to install Python pre-release versions, for example Python 3.13.0rc2 is currently available on conda-forge. When I tried to set the Python version to 3.13.0rc2, I got the error (see GH actions run here):

You need to add the python_rc label channel I think.

dstansby commented 1 month ago

Ah yes, that seems right: https://conda-forge.org/docs/maintainer/knowledge_base/#installing-a-pre-release-build

Do you know how to pass labels to the setup-miniconda action? They don't seem to be mentioned in the README.

dstansby commented 1 month ago

Ah, passing channels: conda-forge, conda-forge/label/python_rc seems to have worked. Would you be open to me adding how to do this to the README of setup-miniconda?

jaimergp commented 1 week ago

Sorry for the delay, yes go for it!
