Dear Juan Luis Cano, Thank you very much for your kind help.
This is the information I got: $ echo $PYTHONPATH $ cd ~/envs/fenics27/share/dolfin/demo/documented/cahn-hilliard/python/ $ python demo_cahn-hilliard.py --------------------------------------------------- DOLFIN runtime dependency is not met. Install the following python module: 'ffc' and make sure its location is listed in PYTHONPATH. --------------------------------------------------- $ cd ~ $ python -c "from dolfin import *" --------------------------------------------------- DOLFIN runtime dependency is not met. Install the following python module: 'ffc' and make sure its location is listed in PYTHONPATH. I think something is wrong with the PYTHONPATH?
