Is there a way to find all Python PyPI packages that were installed with easy_install or pip? I mean, excluding everything that was/is installed with the distributions tools (in this case apt-get on Debian).
There are many ways to find the packages installed with easy_install/pip but some of the important ways I am discussing here:-
The first thing you can use the pip freeze command and it outputs a list of installed packages as well as their versions. The pip freeze command also allows the user to write those packages to a file that can later be used to set up a new environment.
After the release of the pip version 1.3, you can use the pip list command which has some useful options including the ability to show outdated packages.
