How can I install a python .egg file

Question

I am trying to install twisted on python 2.6 and it seems that the Zop interface is missing. Also it seems that it is a .egg file. I downloaded this .egg file, now how can I install it?

Answer 1

Install virtualenv, which includes pip. Then you can simply run:

pip install twisted

pip will handle installing the zope.interface.
