How to Install Pip and packages on Ubuntu 16.04


Share This!

I just started using Python. Just developed a script in Python. It’s fun. I use Ubuntu 16.04 (64-bit) and there was a older version of Python installed on my distro. Had a hard time upgrading it, so I decided to uninstall it and then install the latest version. So, here’s how to install the latest version of Pip (Python) on Ubuntu 16.04:

First of all, update your system

You should always keep your Ubuntu up-to-date with all its packages. To do so, run the following command:

sudo apt-get update && sudo apt-get -y upgrade

This will update everything on your Ubuntu.

Next, install Pip on your Ubuntu

The actual installation process is very simple. Only one command, which is:

sudo apt-get install python-pip

That’s it. Now the latest version of Pip is installed on your Ubuntu. The package manager will install Pip and all other dependencies, so you don’t have to worry about anything.

You can check which version of Python you have installed by executing:

pip -V

An alternative method to apt-get for installing Pip on Ubuntu is using curl and Python.

Using curl and Python to install Pip is also a simple process. First, run:

curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"

Then, run:

python get-pip.py

And that’s it.

How to install packages using Pip

Now that you have Pip installed on your Ubuntu, it’s time to install some packages. You can search for a package using:

pip search packageName

Of course, you should replace packageName and search for whatever package you want. This command will search PyPI for packages with the name you provide.

After you find your desired package, you can install it with:

pip install packageName

And similarly to installing it, you can uninstall it with:

pip uninstall packageName

Running pip --help will give you a list of useful commands you can run with pip and a brief explanation of those commands:
