Hello all; I am using Ubuntu 12.10 and Python v2.7.3. I am trying to add adirectory to the PYTHONPATH. All of the commands I have found on the web have failed. Please help me to add a directory to the PYHONPATH. The filepath is Home/home/bin. Thanks in advance.

What do you mean by that path? That doesn't look like an Ubuntu/Linux
path name. Pull up a terminal (Ctrl-Alt-T should do that for you,
though I haven't used an Ubuntu since 10.10) and see if you can 'ls'
the path - once you have the real path name (it might start with
/home/your_user_name/ for instance), go back to the commands you found
on the web and try them - they'll probably work, then.

thats the file path. the directory "bin" in my home directory. in bash itobviously looks like this "~/bin" using the file system folder the path is home/Home/bin. i have tried commands like, export PYTHONPATH=${PYTHONPATH}:/users/matt/bin or home/matt/bin or Home/home/bin and nothing has worked.
from what ive found on the web the Python import process is notoriously underspecified, notwithstanding i was under the impression that PYTHONPATH is a global variable that i can add directories to at anytime to tell Python where to look, without having to add some sort of code to every program. isthis impression incorrect? is there some code i need to add to the Pythonprogram call the modules in the "bin" dir?

Change to that directory, then type 'pwd'. That'll tell you the actual
path. My guess would be /home/matt/bin - note the leading slash.

What exactly do you mean by "no luck"? More details would be good.

Hi,

Do you run Python in the same terminal than where you run the export
command ?

What is PYTHONPATH actually set to? You can find out by running python
interactively, then

import os
os.environ['PYTHONPATH']

The program i am using (GNU radio companion) that wants to import the modules from the ~/bin folder shows this error:

Block - import_0_0_0 - Import(import):
Param - Import(import):
Import "import multimode_helper as mh" failed.

OK so i ran python and then :

import sys
sys.path

bash returned:

['', '/home/matt', '/users/matt/bin', '/home/matt/bin', '/Home/bin', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PIL', '/usr/lib/python2.7/dist-packages/gst-0..10', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/python2.7/dist-packages/ubuntu-sso-client', '/usr/lib/python2.7/dist-packages/ubuntuone-client', '/usr/lib/python2.7/dist-packages/ubuntuone-control-panel', '/usr/lib/python2.7/dist-packages/ubuntuone-couch', '/usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol', '/usr/lib/python2.7/dist-packages/wx-2.8-gtk2-unicode']

so the paths i have been adding are there. should i be adding the python file names in the "bin" directory as well?
