Installing Chained Dependency With Pip And Requirements.txt?

I am trying to use a requirements.txt file to install a couple of libraries using pip. My problem is that one library (pyfasttext) requires another (Cython) to be installed first.

Solution 1:

The problem is not that pyfasttext requires Cython but that its setup.py imports Cython before installing it. You have to install Cython first yourself.
