TL DR: Starting python setup.py develop --uninstallfrom the environment pypycreated with the toxleads to the exclusion of: error: [Error 32] The process cannot access the file because it is being used by another process: c:\users\shach\code\pydocstyle\.tox\pypy\site-packages\funniest.egg-link.
Hi guys,
I have a set of integration tests for my python package that do the following:
- Call
python setup.py develop(using subprocess.check_call) - Run all tests for the package.
- Call
python setup.py develop --uninstall(again, using subprocess.check_call)
Tests are performed tox. Everything works fine in python versions 27, 33, 34, 35and 36, but the code does not work on pypy.
I'm not going to include the setup.pyproject file here, you can assume that everything is in order. I reproduced this using the minimal package shown here and it works (fails?) Anyway.
To reproduce, I created a python script that runs the following:
import shlex
import subprocess
subprocess.check_call(shlex.split('python setup.py develop'))
print('----------')
subprocess.check_call(shlex.split('python setup.py develop --uninstall'))
Running a file using the usual pypyone installed on the system works very well:

Here tox.iniI use to play:
[tox]
envlist = pypy
[testenv]
commands=python test.py
I made sure that I have read / write permissions to the directory, and I lost my mind a bit.
It works fine on Linux. Probably because you can delete the file you are using ( inodesetc.): ^)
