In virtual environment populated with flit install -s (editable), python3 -m pip freeze raises AssertionError on MacOS

[tombaker]

When I populate a virtual environment with flit install -s, executing python3 -m pip freeze raises Pip's AssertionError.

I described this yesterday on Stackoverflow, then filed a bug report for Pip with detailed instructions on how to reproduce the problem on MacOS 10.15.7 and Ubuntu 20.04.

Since then, however, I have noticed that pip freeze works in virtual environments populated using Flit 2.3.0 but not in environments populating using Flit 3.0.0.

Is this possibly an issue for Flit (and not for Pip)?

@tombaker probably related to #335, but I think the fix should be done in pip.

@sbidoul This has been fixed in pip, so I guess you could close this issue now - thanks!
