Python six module installed but import fails

six is in dependencies and installation looks ok but when starting the python service it looks like it’s not there.
Any ideas about this problem?

python = “3.10.4”

six = “^1.16.0”

Output in logs when starting the app:

2022-06-10T08:23:10.434 app[9fa701eb] fra [info] import six
2022-06-10T08:23:10.434 app[9fa701eb] fra [info] ModuleNotFoundError: No module named ‘six’

I’m having the same problem. I don’t have a diagnosis, but I do have a workaround: Force install with a URL to a package.

poetry add

Not sure why that worked, but it at least unblocked me.
