To be fair, it was Roel Schroeven who posted the steps and the part 
you're quoting here, and others had pointed in the direction of the venv 
not having been activated - I just posted a correction to one of Roel's 
commands.  Sorry, I can't help much with your actual problem, but 
hopefully others can.
