A different one ``` sander@arthur:~/documents/projects/sampleproject$ PYTHONPATH=.env/lib/python3.9/site-packages/ .env/bin/python -m build --sdist * Creating isolated environment (venv)...

I think `venv.EnvBuilder(with_pip=True).create()` needs to be run in isolation from the env vars as well, but I haven't dug deeper than that.

I've run the above command with `build` at `layday/override-leaky-env-vars` (169b154) if that's what you mean. I get the same result.

Ah, I'd misunderstood your earlier comment. The `venv` invocation is indeed a bit trickier than I made it out to be. Do you consider this in scope for #406? I...

I see this is indeed a duplicate, my apologies, I hadn't though to search for flake8, as I considered it specific to my example, not the actual issue.

However, the discussion on that ticket or the comment you linked however don't go into why it rejects `flake8-3.9.2` in the first place. I fully agree that there are multiple...

@uranusjr while I see how your suggestion could be useful, I'm not sure it applies to the issue I'm trying to highlight. As far as I'm concerned, this issue is...

All right, I'll have a look at that. I'm not sure when I'll find the time to do so though, perhaps this weekend. Thanks for your suggestion.

The following test case reproduces the behavior I'm seeing with a simple `Provider`. Not the cleanest implementation (but it will do for a POC) and it doesn't prove the presence...

Thanks for that. I'll have a look at that soon. `parent`, `child` and `grandchild` are representative of `flake8-isort`, `flake8` and `pyflakes` respectively. `child` has two versions, each with their own,...
