pip: 21.3: Breaking editable installation with `No module named pip` error

Description

Our CI is failing due to version 21.3 release, in the pip wheel subprocess call during installation, with seemingly random packages being the culprit.

E.g.

  subprocess.CalledProcessError: Command '['/opt/hostedtoolcache/Python/3.7.12/x64/bin/python', '-m', 'pip', '--disable-pip-version-check', 'wheel', '--no-deps', '-w', '/tmp/tmpiq0bznxg', '--quiet', 'cryptography<3.5,>=3.4.1']' returned non-zero exit status 1.

Full Log attached below

The specific dependency it fails for seems completely random, in 5 subsequent runs it’s been pathspec, cryptography, tabulate, rdflib and pyasn1.

I can reproduce the issue locally as well with Arch Linux, 21.3 fails, 21.2.4 works. This only happens in editable mode (using -e flag), without it everything install fine.

Expected behavior

Renku Package to be installed without problem

pip version

21.3

Python version

3.7.8

OS

Arch Linux/Github Actions(Ubuntu)

How to Reproduce

1. clone https://github.com/SwissDataScienceCenter/renku-python
2. upgrade to pip 21.3
3. do pip install -e .[all]

Output

$ python -m pip install -e .[all]
