02/24/2022, 8:32 PM@high-yak-85899 the interesting info will be the actual contents of that venv. Namely, is the ModuleNotFoundError "correct"? Can you provide a listing of

02/24/2022, 9:20 PMThat would be good to confirm, but besides that this is extremely hard to debug without the snapshot of the filesystem. I'd just file the bug with all these details as well as the version of pytest. Until more data is forthcoming I don't think the issue will bear fruit, but at least there is a central place to collect information.
