How to Downgrade Django on MacOS: A Step-by-Step Guide

If you're a student or a developer, you might find yourself in a situation where a specific version of Django is required for a project or a course. In this guide, we will tackle the common issue of downgrading Django on a MacOS system. Let's take a closer look at how to efficiently downgrade from Django 3.1.5 to version 2.2.17 as per your university requirements.

The Problem

You might have installed Django version 3.1.5 on your Mac, but the course you’re taking specifies a need for version 2.2.17 for testing purposes. When trying to install the desired version using the command pip3 install Django-2.2.17, you encounter an error stating that a newer version is already installed. This can be frustrating, but don't worry; we have the solution for you!

The Solution: Downgrading Django

Why Use Specific Versions of Django?

Before we dive into the steps, you might wonder why it’s important to use specific versions of Django. Different versions may have different features, functionalities, or even bugs. Using the exact version your course recommends ensures compatibility with the class materials and provides a consistent learning experience.

Steps to Downgrade Django
