Here is the solution when you try to install a python package using python setup.py install
or pip install .
and you get the error ImportError: No module named Cython
.
Solution 1
Try to upgrade or install cython in your virtualenv:
pip install --upgrade cython
Solution 2
You can also try to use pip module with python command, make sure you have activated your virtualenv:
python -m pip install --upgrade cython
Solution 3
Some environments could use python3
command instead of just python
:
python3 setup.py install
