Today, I will talk to you about how to install pip in Ubuntu. Many people may not know much about it. In order to let everyone know more, Xiaobian summarized the following contents for everyone. I hope everyone can gain something according to this article.

pip is a command line tool that allows you to install software packages written in Python. Learn how to install pip on Ubuntu and how to use it to install Python applications.

There are many ways to install software on Ubuntu. You can install applications from the Software Center, download DEB files, PPA (Personal Package Archives), Snap packages, use Flatpak, use AppImage, or even install old source code.

There is also a way to install packages in Ubuntu. It is called pip and you can use it to install Python-based applications.

What is pip?

pip stands for "pip Installs Packages." Pip is a command-line based package management system. Used to install and manage software written in Python.

You can use pip to install packages listed in the Python Package Index (PyPI).

As a software developer, you can use pip to install various Python modules and packages for your own Python projects.

As an end user, you may need to use pip to install some Python-developed applications that can be easily installed using pip. One such example is the Stress Terminal app, which you can install easily using pip.

Let's see how to install pip on Ubuntu and other Ubuntu-based distributions.

How to install pip on Ubuntu

By default, pip is not installed on Ubuntu. You have to install it before you can use it. Installing pip on Ubuntu is very easy. I'll show you right away.

Ubuntu 18.04 has Python 2 and Python 3 installed by default. Therefore, you should install pip for both Python versions.

pip, which by default refers to Python 2. pip3 stands for pip in Python 3.

Note: I am using Ubuntu 18.04 for this tutorial. However, the tutorials here should be applicable to other versions, such as Ubuntu 16.04, 18.10, etc. You can also use the same commands on other Linux distributions based on Ubuntu, such as Linux Mint, Linux Lite, Xubuntu, Kubuntu, etc.

Installing pip for Python 2

First, make sure Python 2 is installed. On Ubuntu, you can verify this with the following command.

python2 --version

If there are no errors and valid output from Python versions is displayed, Python 2 is installed. So now you can install pip for Python 2 using this command:

sudo apt install python-pip

This will install pip and its many other dependencies. After installation, make sure you have pip installed correctly.

pip --version

It should display a version number as follows:

pip 9.0.1 from /usr/lib/python2.7/dist-packages (python 2.7)

This means that you have successfully installed pip on Ubuntu.

Installing pip for Python 3

You must make sure Python 3 is installed on Ubuntu. You can check this with the following command:

python3 --version

If a number like Python 3.6.6 is displayed, Python 3 is installed on your Linux system.

Now, you can install pip3 using the following command:

sudo apt install python3-pip

You should verify that pip3 is installed correctly using the following command:

pip3 --version

It should display a number like this:

pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)

This means pip3 has been successfully installed on your system.

How to use the pip command

Now that you have pip installed, let's quickly look at some basic pip commands. These commands will help you use pip commands to search, install, and delete Python packages.

To search for packages from the Python package index PyPI, you can use the following pip command:

pip search

For example, if you search for the word "stress," all packages that contain the string "stress" in their name or description will be displayed.

pip search stressstress (1.0.0) - A trivial utility for consuming system resources.s-tui (0.8.2) - Stress Terminal UI stress test and monitoring toolstressypy (0.0.12) - A simple program for calling stress and/or stress-ng from pythonfuzzing (0.3.2) - Tools for stress testing applications.stressant (0.4.1) - Simple stress-test toolstressberry (0.1.7) - Stress tests for the Raspberry Pimobbage (0.2) - A HTTP stress test and benchmark toolstresser (0.2.1) - A large-scale stress testing framework.cyanide (1.3.0) - Celery stress testing and integration test support.pysle (1.5.7) - An interface to ISLEX, a pronunciation dictionary with stress markings.ggf (0.3.2) - global geometric factors and corresponding stresses of the optical stretcherpathod (0.17) - A pathological HTTP/S daemon for testing and stressing clients.MatPy (1.0) - A toolbox for intelligent material design, and automatic yield stress determinationnetblow (0.1.2) - Vendor agnostic network testing framework to stress network failuresrusstress (0.1.3) - Package that helps you to put lexical stress in russian textswitchy (0.1.0a1) - A fast FreeSWITCH control library purpose-built on traffic theory and stress testing.nx4_selenium_test (0.1) - Provides a Python class and apps which monitor and/or stress-test the NoMachine NX4 web interfacephysical_dualism (1.0.0) - Python library that approximates the natural frequency from stress via physical dualism, and vice versa.fsm_effective_stress (1.0.0) - Python library that uses the rheological-dynamical analogy (RDA) to compute damage and effective buckling stress in prismatic shell structures.processpathway (0.3.11) - A nifty little toolkit to create stress-free, frustrationless image processing pathways from your webcam for computer vision experiments. Or observing your cat.

If you want to install an application using pip, you can use it as follows:

pip install

Pip does not support tab completion of package names, so package names need to be specified accurately. It will download all necessary files and install the package.

If you want to remove Python packages installed via pip, you can use the uninstall option in pip.

pip uninstall After reading the above, do you know more about how to install pip in Ubuntu? If you still want to know more knowledge or related content, please pay attention to the industry information channel, thank you for your support.
