installation of easybuild-easyconfigs fails because easybuild/easyconfigs/p/path.py is not a regular file

[pjf295]

I am trying to install easybuild on centos 7.9. I made a new environment within miniconda for the installation, but encountered an error while trying a pip install of easybuild. Here is the environment:

$ python -V
   Python 3.10.4

$ type module
  module is a function
  module () 
  { 
      eval $($LMOD_CMD bash "$@") && eval $(${LMOD_SETTARG_CMD:-:} -s sh)
  }

$ type -f module

  -bash: type: module: not found

$ module --version

@pjf295 We briefly discussed this in the EasyBuild Slack.

This error is positively bizarre:

error: can't copy 'easybuild/easyconfigs/p/path.py': doesn't exist or not a regular file

I mentioned in Slack that there's no such file in the easyconfigs package, but it seems like that's not entirely correct: we have a directory named path.py, see https://github.com/easybuilders/easybuild-easyconfigs/tree/develop/easybuild/easyconfigs/p/path.py .

I suspect this is tripping up pip or conda somehow, because it's making an assumption somewhere that something ending in .py must be a Python file perhaps?
I consider that a bug in whatever package is responsible for that error (perhaps setuptools?)...

[boegel]

This problem should be fixed in EasyBuild v4.5.5, thanks to the changes in easybuilders/easybuild-easyconfigs#15206, so closing...
