You see the error: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio in there?

Have you tried installing the Build Tools for Visual Studio?

Hello @sohailiqbal, What version of Python are you using? I just uploaded the Windows binaries for Python 3.6 and 3.7 to pypi, so you shouldn't have to build it from source if you're using one of those versions. Try pip install again and let me know if the issue persists. Actually, I'm curious to know if this doesn't work if you have Python 3.6 or 3.7, so please let me know. Regardless, as @sauln said, you can build from source if you have Build Tools for Visual Studio, which are freely available online

Dear Chris Tralie,

I am sorry for the late reply. The problem is resolved with python 3.7.

In fact I was using python 3.8, I installed Build Tools for Visual Studio but that did not work either in this case.

Thanks for your help.

Best, Sohail
