Help with Python package (virtualenvwrapper)

[Steve George]

Hi,

I'm working on creating packages for virtualenvwrapper. I'm having 
problems with the 'check' phases of both packages and could do with some 
help ...

I think I have the correct inputs for virtualenvwrapper, the package 
definition is below. The error I get is:

error: in phase 'check': uncaught exception:
%exception #<&invoke-error program: "python" arguments: ("-c" "import 
setuptools, tokenize;__file__='setup.py';f=getattr(tokenize, 'open', 
open)(__file__);code=f.read().replace('\\r\\n', 
'\\n');f.close();exec(compile(code, __file__, 'exec'))" "test") 
exit-status: 1 term-signal: #f stop-signal: #f>

build of 
/gnu/store/2wa2kwafx63780wnk93gbx6xr2ms7kjq-python-virtualenvwrapper-4.8.4.drv 
failed

In the build log I can see this sort of error:

File 
"/gnu/store/65i3nhcwmz0p8rqbg48gaavyky4g4hwk-python-3.9.9/lib/python3.9/site-packages/pkg_resources/__init__
.py", line 1379, in __init__
    self.module_path = os.path.dirname(getattr(module, '__file__', ''))
  File

line 152, in dirname
    p = os.fspath(p)
TypeError: expected str, bytes or os.PathLike object, not NoneType

Does anyone know how to debug this further, or has run into this sort of 
problem?

The build command I'm using is:

  guix build --file=python-virtualenvwrapper.scm --keep-failed

Here's the package definitions that I have:
