[New-bugs-announce] [issue22611] pip needs ctypes

[Antoine Pitrou]

New submission from Antoine Pitrou:

I think a bit weird that pip needs ctypes inconditionally. Note the following traceback is on an Unix platform and ctypes seems imported by a... win32 shell coloring library!

======================================================================
FAIL: test_with_pip (test.test_venv.EnsurePipTest)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/export/home/buildbot/64bits/3.x.cea-indiana-amd64/build/Lib/test/test_venv.py", line 356, in test_with_pip
    with_pip=True)
subprocess.CalledProcessError: Command '['/tmp/tmppsirrkh8/bin/python', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1

During handling of the above exception, another exception occurred:
