Can someone help me? I think that is related a compiler c in my machine, and is not able to compile, but I had installed a lot of things in past without problem.

Answer 1

phd's answer didn't fix it for me. Installing cython manually did the trick:

pip install cython

Answer 2

The fuzzyset package at PyPI lacks the file fuzzyset/cfuzzyset.c. It's a bug in the package, already reported.

Your only chance for now is to install from github:

pip install git+https://github.com/axiak/fuzzyset.git#egg=fuzzyset
