问题
I am writing a web based app based on python and django. I have a source code folder containing LIBS directory that has a file named utils.py. When I want to install my app a new line is added to ~/.profile file like export PYTHONPATH=$PYTHONPATH:/home/test/src/LIBS (The path is added based on the installation path) When I run the below code in the interpreter the path is OK:
import sys
sys.path
['', '/usr/lib/python2.7', '/home/test/src/LIBS', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/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/pymodules/python2.7']
Unfortunately, when i want to load the home page of my app the line that imports utils raises an exception
What i do wrong? Thanks in advanced.
回答1:
Your ~/.profile only adds the dir to the PYTHONPATH in the current shell environment. It's not globally available. When django loads, it uses the wsgi.py and another project path.
The easiest way to add a globally available path is to add a .pth file. It should be in your python dist-packages directory (depends on the OS):
$ sudo nano /usr/lib/python2.7/dist-packages/
/home/test/src/LIBS
And save the file.
Now the app will be available for all python instances on your machine.
If you want to add this path only to a specific django project, in the wsgi.py add:
import sys
sys.path.append("/home/test/src/LIBS")
