Cadquery import issue "cannot import name 'TypeGuard" #1064

Closed tommy3001 closed 2 years ago

tommy3001 commented 2 years ago

To Reproduce

I can not import cadquery anymore. I installed only a few additional packages.

The version is the actual master branch installed with

conda install -c cadquery -c conda-forge cadquery=master

Backtrace

Traceback (most recent call last): File "/home/tommy/miniforge/lib/python3.9/site-packages/nptyping/assert_isinstance.py", line 33, in from typing import TypeGuard ImportError: cannot import name 'TypeGuard' from 'typing' (/home/tommy/miniforge/lib/python3.9/typing.py)

During handling of the above exception, another exception occurred:

Ok, got it. It has something to do with the now solved bug #1050. I downgraded to nptyping 1.4.4 as a workaround a few days before, which is now obsolete. After reset of the environment and using nptyping 2.0.0, it is solved.
