OK, the problem is due to several /usr/local/lib/python2.7/dist-packages/ before /usr/lib/python2.7/dist-packages (where system package modules are installed). I suppose you had to install manually something, but the problem is that mixing system package with manually installed packages can lead to situation like the one you discovered. If you tell Python to ignore site-specific configuration hook, you should be able to confirm this. Just call python with -S. For example: python -S -c "import sys; sys.path.append('/usr/lib/python2.7/dist-packages/'); import requests; print requests.__version__" 2.10.0 Note that you have to explicitly add '/usr/lib/python2.7/dist-packages/' to sys.path. So, to solve the problem you should get rid of the local installed packages that lead to this situation, but since it can be tricky to find packages who meddle with system packaged ones, it would better (and easier) to just remove all of them (manually installed I mean) and use, for example, a virtualenv for packages not in Debian, to not have to worry about mixing packages from different source.
