pypi release 0.0dev38 vs 0.0dev0 meta data conflict

[jamienoss]

Hey @Johannes-Sahlmann

I believe the following line https://github.com/spacetelescope/pystortion/blob/master/setup.cfg#L45
may be causing the following error that I'm seeing from a Windows CI build - https://github.com/spacetelescope/catkit/pull/163/checks?check_run_id=1493301452#step:5:1045

ERROR: Requested pystortion from https://files.pythonhosted.org/packages/93/9e/4539dc20a2057ae0b5c2c6a03554df59944d8e85982f869a7b825166adc6/pystortion-0.0.dev38.tar.gz#sha256=81b3d11f047ef2d1de1cf6e2f3cd2ac020ae3b54641e5c9c0f3b362d5ccb15ad (from -r D:\a\catkit\hicat-package\condaenv.678inxdy.requirements.txt (line 5)) has different version in metadata: '0.0.dev0'

Any thoughts?

Cheers,
Jamie

Hi @jamienoss , first time I am seeing something like this.

One possible solution could be to make a release of this package where that 0.0.dev0 is set to a proper version number, and then change your dependency to include the version number explicitly.

Looks like this is a rather frequent problem now which is related to more strict checking in new versions of pip:
see e.g. pypa/pip#8745
espnet/espnet#2736

Forcing pip==20.2.4 in my dependencies made the error go away in a small local test that I performed.
