Append single package folder to sys.path

Question

I use a script under virtualenv, that requires bzrlib package which is not available in my virtualenv but is included in my system python packages: /usr/lib/python2.7/dist-packages/bzrlib/

If I want to use it, one option is to extend sys.path, but I would have to include the parent folder /usr/lib/python2.7/dist-packages/ which contains many other packages, that I don't want to make available. Is there any easy way to include just bzrlib package?

Answer 1

What about creating a link in different directory and importing using that? Or even in your own project.

ln -s /package/dir/path /project/dir/path

If you have to load it remotely, here is the link provided by @unutbu showing how to do it:
