Hi Lawrence, thanks, I managed to fix it. It turns out that in the past I had installed coffee with ‘python setup.py build’, and my python path was still pointing to this directory, i.e. when I updated coffee, it was still using the old version. I now just set the python path to the COFFEE directory, is there any point in running ‘python setup.py build’ anyways, or does it just copy the source files to build?
