How to update/upgrade a package using pip?

What is the way to update a package using pip? These commands do not work: pip update pip upgrade I know this is a simple question but it is needed as it is not so easy to find (pip documentation doesn't pop up and other questions from stack overflow are relevant but are not exactly about that)
This is the way pip install <package_name> --upgrade or in short pip install <package_name> -U Using sudo will ask to enter your root password to confirm the action, but although common, is considered unsafe. If you do not have a root password (if you are not the admin) you should probably work with virtualenv. You can also use the user flag to install it on this user only. pip install <package_name> --upgrade --user
