Peak list and sudo pip list show different package versions

I have a Mac, I installed Python with Homebrew

and I installed packages with pip

. But I found out when I call pip list

and sudo pip list

, it actually gives different versions of the packages. For example, I have ipython (3.1.0) in sudo pip list

and ipython (2.3.0) for only pip list

. What does it mean? Do I have both versions?

The reason I found out about this is because when I update some packages my system denied permission, so I used sudo

, did I do it wrong?

The answer is pretty simple: your python environment uses different paths. to do

$ which pip
$ sudo which pip


and you get two different paths.

Consider seriously switching to using python virtualenv, which will make your management much easier.
