Install problems with python 3.7.3

[andrzejnovak]

Seems to be a problem with installing distributed.

Error message below:

Yes, is this package dead? The readme suggests it should work with python 3 but I cannot install it under
Python 3.9.7 (default, Sep 10 2021, 14:59:43)
[GCC 11.2.0] on Ubuntu 21.04.
I get an infinite loop of errors, like:

 python3 -m pip install --user pyqt-fit

and then it fails again with the cached version and keeps repeating.

Hello,

This module uses cython so you need a C++ compiler. If you follow the instruction on this link([https://wiki.python.org/moin/WindowsCompilers]) you should be able to go past that error and import the module with pip.
I've gone with Microsoft Visual C++ but I still get an error after that when importing pyqt_fit :

CompileError: command 'C:\\Program Files\\Microsoft Visual Studio\\2022\\Community\\VC\\Tools\\MSVC\\14.31.31103\\bin\\HostX86\\x64\\cl.exe' failed with exit code 2

I'm curious if you have the same error.
