Installing style50 on windows - pip

Question

I was trying to install style50 on windows (having MSYS2) using pip install style50 , the concluding message doesnt mention of anything failing. But thereafter when I run style50 --version for verifying, I get the following error(2):
$ pip install style50

Answer 1

As per the documentation on Github (emphasis mine):
Along with most of CS50's command line tools, style50 supports being run on Windows but only via the Linux Subsystem in Windows 10. After launching it, style50 can be installed using the pip command above.
