Re: Permanently adding to the Python path in Ubuntu
When I wanted to set PYTHONPATH I had the advantage of knowing nothing about how Linux/Ubuntu was supposed to work, so I tried everything. ~/.profile worked for me.

Re: Permanently adding to the Python path in Ubuntu
I don't want to have to modify the path in each and every application. There has to be a way to do this... Personally, I don't agree with the Debian maintainers in the order they import anyway; it should be simple for me to overshadow system packagers. But that's another story. P.S. my first name is Steven! Cheers, Chris On Sat, Aug 29, 2009 at 11:51 PM, Sean DiZazzo wrote: > On Aug 29, 5:39 pm, Chris Colbert wrote: >> I'm having an issue with sys.path on Ubuntu.

Maybe this will work (at the top of your script): import sys sys.path[0] = "/usr/local/lib/python2.6/dist-packages" import numpy PS.
