Any suggestions why version 4 throws that?

pip3 install fire installs 0.3.1 for me

What environment are you on? I wasn't able to recreate on windows

It appears this could be related to python versions and windows environments

I'm going to close this since it doesn't appear to be a fire related issue.
Please do share the resolution if you find it though.
