tests session in nox fails with an ImportError

[AliSajid]

Hi,

I am working on a brand new project and created a project with the latest cookiecutter template. However, with nothing added, it still fails in the nox sessions for tests and typeguard.

The error seen is given below but it boils down to not being able to import the package I am building.

 ➜ poetry run nox -rs tests-3.10

Things I have tried

• I have tried cleaning out any rogue python installations on my system
• I have removed and reinstalled cookiecutter, poetry and pyenv and the python versions (3.7-3.10)
• Recreated the project from scratch. Twice.
