回答1:

While Kugel's answer is perfectly valid, I would also urge you to avoid system wide install, and to use a virtualenv. It will allow you to create a sandbox for your project and isolate it from others.

When creating a virtualenv, you can specify the Python interpreter version you want to use. For example, for python2.7:

$ virtualenv path/to/project -p /usr/bin/python2.7

Then, a pip install command will automatically install the package for python2.7.

1. The package you mention is corrupted / incomplete. Download source code from here and you can see there is only setup.py and no other source code. Beside that, the homepage is a broken link.

2. To install for a different version of python use pip-2.7 install xxx. There is usually a pip-x.y for each python version you have installed.
