Why doesnt pip install bitarray work for me?

Question

So I am trying to use pip install bitarray but that results in a error, even I can't really understand. I have had this issue a while already with few other packages, today I installed a virtual environment and I tried to code again. I tried to install the package outside of this venv but I get the same error.

Collecting bitarray
Using cached bitarray-2.1.0.tar.gz (71 kB)
Using legacy 'setup.py install' for bitarray, since package 'wheel' is not installed.
Installing collected packages: bitarray
    Running setup.py install for bitarray ... error

Please format console output as code. The current formatting makes it illegible — Mad Physicist, Jun 07 '21 at 11:51

This part

Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/

suggest that you should install Microsoft Visual C++ 14.0 before installing bitarray. bitarray's PyPI page hints that you need working C compiler before installing bitarray.

Thanks! The error message is gone by now, but I am still getting a notification under "Problems" `Import "bitarray" could not be resolved Pylance(reportMissingImports) [2, 8]` Update: I had to change the python interpreter from the venv to the python.exe, this way it works! – dnnsqe Jun 07 '21 at 12:39
