"Pip install opclabs_quickopc" fails in PyCharm

Hello.

This happens when "long paths" are not enabled on Windows. 

1. Exit PyCharm.
2. Enable long paths. There are multiple ways to do it (Google...). One of them - the one I used when I now reproduced your problem - was:  www.autodesk.com/support/technical/article/caas/sfdcarticles...AX-PATH-is-256-characters.html .
3. Start PyCharm and retry.

I hope this helps.
Best regards

I am using PyCharm, but underlying python is 3.13 and pip is 25.0.1.  I have also tried running PIP directly from CMD window.   If it matters, the initial error message is:

  × Building wheel for opclabs-quickopc (pyproject.toml) did not run successfully.

I have tried on multiple computers, multiple Administrator accounts, and still always the same result.  What am I doing wrong?

Thanks.

Hello.
Which version of pip, and which version of Python are you running?

I could not reproduce the issue. I tested with pip 25.0.1, and Python 3.13.3.

Best regards

When I type pip install opclabs_quickopc in the terminal of PyCharm, I get the message "ERROR: Failed building wheel for opclabs_quickopc".  This message is preceded by a large number of messages like this:

('C:\\Users\\steve\\AppData\\Local\\Temp\\pip-modern-metadata-1dihd12h\\opclabs_quickopc-5.82.175.dist-info\\licenses\\opclabs_quickopc\\OpcLabs.QuickOpc\\System.Security.Cryptography.ProtectedData_6.0.

nnot find the path specified')

Any ideas?
