On archlinux, the vim installed with pacman does not have python enabled, thus I compiled it myself. But when I open a .py file with the self-compiled terminal-vim, I come into some error like this:

Error detected while processing /home/coin/.vim/bundle/python-mode/autoload/pymo
de/lint.vim:
line    1:
  File "/home/coin/.vim/bundle/python-mode/pymode/lint.py", line 9, in <module>

I tried to enable python2, python3 and both of them when I compile it, but the problem is always their.

Something that might be useful is that, on the platform of archlinux, type "python" in the terminal means to run python3 interpreter while type "python2" means to run python2 interpreter.
