What is the way to update a package using pip? those 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)
The way is
pip install <package_name> --upgrade
or in short
pip install <package_name> -U
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
For a non-specific package and a more general solution, you can check out pip-review. A tool that checks what packages could/should be updated.
$ pip install pip-review
$ pip-review --interactive requests==0.14.0 is available (you have 0.13.2) Upgrade now? [Y]es, [N]o, [A]ll, [Q]uit y
use this code in teminal :
python -m pip install --upgrade PAKAGE_NAME #instead of PAKAGE_NAME
for example i want update pip pakage :
python -m pip install --upgrade pip
more example :
python -m pip install --upgrade selenium python -m pip install --upgrade requests ...
