I see we will not agree, and this thread is mostly dead anyway, but for posterity: it sounds like you haven't installed mypy into the venv you're using. I can see how that would not work. I don't try and reference python scripts that I haven't installed using the venv so perhaps that's why I've never encountered this situation. If it's part of my project it's installed into the venv (and if it's a dev dependency like mypy, which I do use, it gets installed as a dev dependency so it doesn't end up in releases).
