Installation and Updating of Cython

How to update and install cython in FEMhub

Use these instructions if your FEMhub installation failed with an error “Cython too old”. Firstly, go to the directory where you have all your repositories (such as /home/pavel/repos/). Then, in your terminal type:

git clone https://github.com/cython/cython.git
cd cython
femhub --shell
python setup.py install

Note: If FEMhub is not found, then you need to add the path of your local femhub directory to your “PATH” variable in the .bashrc file:

export PATH=${PATH}:/home/pavel/repos/femhub/

How to update and install cython (outside of FEMhub)

Go to the directory where you have all your repositories (such as /home/pavel/repos/). Then, in your terminal type:

python setup.py install --home=~/usr

Add the path of cython to your “PATH” and “PYTHONPATH” variable in your .bashrc file:

export PYTHONPATH=.:$HOME/usr/lib/python:$PYTHONPATH
