No module named 'exceptiongroup' about pytest HOT 6 CLOSED

Okay I see what's happened.

For some reason, the exceptiongroup dep from this project did not install.

The dep. is listed here

same install problem here on python3.10 why this external dependency in the first place? especially in light of recent supply chain attacks

@whateverforever You'll need to install pytest properly then, this it not a pytest issue. I feel like I'm stating the obvious here, but the response to supply chain attacks is not to stop using dependencies altogether and reinventing the wheel every time. The dependency is used to provide support for exception groups on older Python versions.

sure, every dependency is used for something. but why use a python3.11 feature if you want to support older versions? there are dependencies on which you depend, and there is fluff.

You're free to use Python 3.11, in which case the backport isn't installed. 🤷

Just to clarify: we need to support the Python 3.11 feature in the same code base, that's why the backport is used. Note also that users in older versions might also be using the backport, in which case pytest will work as well.
