for some reason, ' ' value (empty value) was added to my sys.path array and I can't run 'setup.py install'. I can't find a way to remove it permanently. I did it through python shell:
sys.path.remove('')
and it removes it until closing the shell. I couldn't find a good answer for permanent removing. I did find this - What sets up sys.path with Python, and when? but I'm sure there must be a better way.
