• Method 1: Upgrade manually one by one

---

pip install package_name -U

• Method 2: Upgrade all at once (high chance rollback if some package fail to upgrade

---

pip install $(pip list --outdated --format=columns |tail -n +3|cut -d" " -f1) --upgrade

• Method 3: Upgrade one by one using loop

---

for i in  $(pip list --outdated --format=columns |tail -n +3|cut -d" " -f1); do pip install $i --upgrade; done

Answer 2

The best way I've found is to run this command from terminal

sudo pip install [package_name] --upgrade

sudo will ask to enter your root password to confirm the action.

Note: Some users may have pip3 installed instead. In that case, use

sudo pip3 install [package_name] --upgrade

Answer 3

To automatically upgrade all the outdated packages (that were installed using pip), just run the script bellow,

pip install $(pip list --outdated | awk '{ print $1 }') --upgrade

Here, pip list --outdated will list all the out dated packages and then we pipe it to awk, so it will print only the names. Then, the $(...) will make it a variable and then, everything is done auto matically. Make sure you have the permissions. (Just put sudo before pip if you're confused) I would write a script named, pip-upgrade The code is bellow,

#!/bin/bash
sudo pip install $(pip list --outdated | awk '{ print $1 }') --upgrade

Then use the following lines of script to prepare it:

sudo chmod +x pip-upgrade
sudo cp pip-upgrade /usr/bin/

Then, just hit pip-upgrade and voila!

Use pipupgrade!

$ pip install pipupgrade
$ pipupgrade --latest --interactive

pipupgrade helps you upgrade your system, local or packages from a requirements.txt file! It also selectively upgrades packages that don't break change. Compatible with Python2.7+, Python3.4+ and pip9+, pip10+, pip18+.

pip install -U $(pip list --outdated | awk 'NR>2 {print $1}')

Answer 6

In Juptyer notebook, a very simple way is

!pip install <package_name> --upgrade

So, you just need to replace with the actual package name.
