The following sequence leaves folders behind in site-packages (master)

[abn]

On my machine, the following sequence leaves folders behind in site-packages:

Install b from path:

$ poetry@3940 add ../b/

Updating dependencies
Resolving dependencies... (0.1s)

Writing lock file

Package operations: 1 install, 0 updates, 0 removals

  • Installing b (0.0.0 /home/fredrik/code/repos/b): Building...

Then I wanted to see what happens if I try to add it again but with the --editable arg:

$ poetry@3940 add --editable ../b/

Updating dependencies
Resolving dependencies... (0.1s)

Writing lock file

Package operations: 0 installs, 1 update, 0 removals

  • Updating b (2.1.3.dev0+g77bcc5e.d20210417114942 /home/fredrik/code/repos/b -> 0.0.0 /home/fredrik/code/repos/b)

Finally uninstalling b:

$ poetry@3940 remove b
Updating dependencies
Resolving dependencies... (0.1s)

Writing lock file

Package operations: 0 installs, 0 updates, 1 removal

  • Removing b (0.0.0 /home/fredrik/code/repos/b)

But unfortunately, b was not completely removed, likely due to the fact that I was able to run poetry add twice:

And now it seems the .venv is b0rked, as there is suddenly a None package:

$ poetry@3940 show

  TypeError

  expected string or bytes-like object

       26│ def canonicalize_name(name: str) -> str:

       30│ def module_name(name: str) -> str:

This is likely related to #3900.

[fredrikaverpil]

This can be reproduced by just doing this:

poetry add /path/to/mypkg
poetry remove mypkg

I don't know if you want to do it like this, but at least this patch actually fixes the issue: #3967
The solution was to add the direct_url.json to RECORD, after the .json file was created.

But something tells me importlib is supposed to scan for this file, and add it to RECORD if it detects it?
I've reached out here and asked if this file should be added to RECORD.
