Upgrade pip to newest version on Ubuntu 16.04

I'm trying to upgrade pip into the newest version (old version 9.0.1 and newest version 19.3.1. using the following commands.

pip install --upgrade pip
sudo apt-get upgrade pip

But it won't upgrade it with the following error:

**$ pip install --upgrade pip**
Collecting pip Using cached
Installing collected packages: pip Found existing installation: pip 9.0.1 Uninstalling pip-9.0.1: Successfully uninstalled pip-9.0.1 Rolling back uninstall of pip

Here's my number one tip: Do not use sudo with pip. You don't need it.

Instead, use a user-level Python distribution installed via pyenv. That way you don't risk yourself messing around with system-level frameworks (and hence creating a problem removing dependencies etc.).

Install Pyenv

All you have to do is:

• Run the pyenv installer
• Follow the instructions
• Install the Python versions you need
• Choose which Python version you want to use for a given directory, or globally

For example, to install 3.7, check which versions are available:

pyenv install -l | grep 3.7

Then run:

pyenv install 3.7.4

Switch to the new version

Now, you can choose your Python version:

pyenv global 3.7.4

This switches your python to point to 3.7.4. If you want the “old” system python, run:

pyenv global system

To check which Python versions are available, run pyenv versions.

Upgrade pip

Once you've switched to a Pyenv version, you can run pip without sudo, and install/upgrade packages easily — without interfering with your system Python:

pyenv global 3.7.4
pip install --upgrade pip
pip install numpy

Do not use apt-get to update pip. The newest version of pip available through apt-get is old.

Quick solution:

As @kenorb is saying in the comments, you can upgrade pip using pip with sudo like this:

sudo pip install --upgrade pip

Proper solution:

Use pyenv - see the answer by @slhck
