How to update / update a package using pip?

Question

How to update a package using pip? those do not work:

pip update
pip upgrade

I know this is a simple question, but it is necessary because it is not so easy to find (pip documentation does not appear, and other questions are relevant because of, but not quite about that)

Answer 1

Way

sudo pip install [package_name] --upgrade

or shorter

sudo pip install [package_name] -U

sudo asks you to enter the root password to confirm the action.

If you do not have a root password (unless you are an administrator), you should probably work with virtualenv, and then you should remove sudo:

pip install [package_name] --upgrade

Answer 4

For a non-specific package and a more general solution, you can use pip-review , a tool that checks which packages can / should be updated.

$ pip-review --interactive
