update python modules

How can I update all python modul开发者_如何学Pythones I have installed on ubuntu?

Ubuntu's repositories usually contain up-to-date versions of Python modules (prefixed with python-) and if you do an apt-get dist-upgrade will update any that you've installed from the repos.

As for packages you may have installed with easy_install, you could use distribute to upgrade them.

Alternatively, you can construct a list of packages you have installed with yolk, and pass the packages in the list from yolk -l to easy_install.

Here is a one click simple command to do so:

pip freeze --local | grep -v '^\-e' | cut -d = -f 1  | xargs sudo pip install -U

Checkout setuptools (a/k/a "easy_install"), the classic way of doing it, or distribute, the new way to handle all your Python module installation needs.
