If you want to avoid nasty version conflicts between your projects, you definitely need to set up a virtual environment. A virtual environment is simply a container separating projects which may have different library version requirements. It is very easy to set up a virtual environment so, there is absolutely no reason not to set up one.
Prerequisite: How to install Python 3, the easiest way.
This is how to setup virtual environment. Open Terminal then, install virtualenv with the following command. (On Windows, use PowerShell or equivalent)
pip install virtualenv

List folders within your current working directory with ls.

Make a folder using mkdir, then change directory into the newly made directory.
Usually, you should keep all your local source code inside a directory called Projects for housekeeping but this is not required. I keep my local codes in /Documents/Projects/ which syncs between my workstation and laptop with iCloud. Good for working remotely without using GitHub.
mkdir MY_PROJECT cd MY_PROJECT

You should see your environment name in your Termina. Check your python version with:
You should see Python 3.x.x if not, read: How to solve my python virtual environment version is no version 3
Now, install the latest version of Django with:
pip install django
Congratulations! You have installed the latest version of Django within a virtual environment. Next, we’ll create our first Django Project in How to create your first Django Project.
