Installing python-crfsuite fails with [WinError 2] The system cannot find the file specified

Question

I tried to install

$ pip install python-crfsuite

Any ideas on what is causing the error: [WinError 2] The system cannot find the file specified and the subsequent failure of the compile step with error 1?

What are my options to fix it? Or is using pip install not the correct way of installing python-crfsuite?

Probably far too late, but for anyone else who finds this page here's the solution...

I got the same error output you did, but a coworker of mine got the below output. That's how we found the solution.
