No module named Cython.Distutils

I am getting the following error when try to install fastthreadpool library from pypi. Suspect that setup.py does not have a dependency on Cython. If Cython installed prior to fastthreadpool, no error below happens.

$ pip install fastthreadpool

Hmm. It looks like

fastthreadpool/setup.py

Line 129 in b7dc56d

cmdclass={'build_ext': build_ext_subclass}, install_requires=['Cython'],

has dependency on Cython. Not sure why it does not work for me...

I always end up building from source when I use this in a project. Make sure g++ is installed in your system. Then:
git clone https://github.com/brmmm3/fastthreadpool.git
cd fastthreadpool
pip3 install -r requirements.txt
python3 setup.py install
