Two Python instances, same libraries

I currently have both Python 2.6 and 2.7 running on my Linux machine.

Now, from Python 2.7, I can't access the libraries that I installed through package manager for Python 2.6.

I tried uninstalling the library and installing it back with Pytho开发者_StackOverflow社区n 2.7 installed as my default runtime. No luck.

How can I share libraries between two Python instances? Is there a more correct way to do this than just copying them?

If useful: my Linux distro is Debian, and my package manager is apt.

You should be able to install the files to an external location and define the environment variable PYTHONPATH to point to the directory that contains the modules.

You should have now both a /usr/lib/python2.6 folder and a /usr/lib/python2.7. Try creating links inside the 2.7 folders to the required files or folders inside the 2.6 folder.
