Python import modules from other packages

问题

Python will by default be looking for modules from lib/python2.7/site-packages But I'm now trying to import packages from other directories on HPCC, which I have to rely on, because I've no root access, it'll be difficult to install myself.

But my question is: how to import modules from other directories?

I've tried:

export PYTHONPATH="/path/to/import/modules:$PYTHONPATH"

But it's not working. What should I do? Thanks

=========================================

My python to use is 2.7.9 ,so I've already set in .bash_profile:

export PATH="/share/pkg/python/2.7.9/bin:$PATH"

2.7.9_packages is the directories containing modules(you could see those folders) I want:

but you could see 2.7.9_packages and 2.7.9 are under the same path.

回答1:

Where to place your own modules:-

1. Place your modules in one of the directories that python normally searches
2. Place all modules in same directory as your program
3. Create a directory/directories that will hold your modules and modify sys.path

I am sure the third option is exactly what your looking for

You can modify sys.path in various ways

• Hardcode PYTHONPATH environment variable in your program code

• Using .pth method

  Create a new file eg myModules.pth and place it in path specified by sys.prefix on windows the content of myModules.pth can be

  c:\My Documents\python\modules

That means you can place your path for that specific module you want to import there
