“How To Override The Pip Command To Python3.X Instead Of Python2.7?” ~ bbaz
Introduction
Python is one of the most popular programming languages in the world. Many developers are using Python 2 for their projects, but its official support has ended. This means that it is necessary to upgrade to Python3.x. However, some developers might face difficulties during the upgrade process, especially when it comes to overriding pip command. In this article, we will provide a step-by-step guide on how to override pip command during the upgrade process.
What is Pip Command?
Pip is a package management system used to install and manage software packages written in Python. It is used to install third-party libraries and frameworks for use in Python projects. Pip is pre-installed in Python distributions above version 3.4. However, sometimes it might not work properly during the upgrade process.
Comparing Python2 and Python3.x
There are several differences between Python 2 and Python3.x. Some of these include:
- Print statement: In Python 2, the print statement is not a function and does not require parentheses to be used. In Python3.x, the print statement is a function and requires parentheses to be used.
- Unicode Support: Python 2 uses ASCII as default encoding, while Python3.x uses Unicode as a default encoding.
- Packages: Some packages are not backward compatible with Python 2, so upgrading to Python3.x will allow you to use updated versions of these packages.
Override Pip Command in 10 Steps
Here are ten steps to override the pip command during the upgrade process:
Step 1: Check Current Version of Python
Start by checking your current version of Python. This can be done by typing python –version in the terminal.
Step 2: Check for Available Packages
Check for available packages, which can be installed by running pip list.
Step 3: Upgrade Pip Package
Upgrade pip package by running pip install –upgrade pip.
Step 4: Check Installed Packages
Check installed packages by running pip freeze.
Step 5: Create Virtual Environment
Create a virtual environment by typing python -m venv env.
Step 6: Activate Virtual Environment
Activate the virtual environment by running source env/bin/activate.
Step 7: Install Required Packages
Install required packages by running pip install -r requirements.txt.
Step 8: Check Installed Packages in Virtual Environment
Check installed packages in the virtual environment by running pip freeze.
Step 9: Deactivate Virtual Environment
Deactivate the virtual environment by running deactivate.
Step 10: Remove Old Python Version
Remove the old Python version by typing sudo apt-get remove python2.7.
Conclusion
Upgrading to Python3.x is necessary to stay up to date and use new features of this programming language. When upgrading, it is essential to know how to override the pip command. The steps provided in this article will help developers during the upgrade process. It is important to take note that some packages might not be backward compatible with Python2, so it’s better to check them before upgrading. Overall, upgrading to Python3.x will provide better performance, security, and support for modern libraries and frameworks, making it worth the effort.

Python3 introduced some breaking changes and new features compared to Python2.
Python2 is no longer supported, and Python3 has better performance and security features.
You can run python –version in your terminal to check your current Python version.
Pip is a package manager for Python packages.
You can run pip install –upgrade pip in your terminal to upgrade Pip.
You can run python3 -m venv myenv in your terminal to create a virtual environment.
You can run source myenv/bin/activate in your terminal to activate your virtual environment.
You can run pip install package_name in your activated virtual environment to install packages.
You can create a file named pip in your virtual environment’s bin directory with the following content:
- #!/bin/bash
- python -m pip $@
Then, make the file executable by running chmod +x bin/pip.
You can run which pip in your activated virtual environment to check if Pip command is overridden.
