1. Create a virtual environment
A virtual environment keeps the coding environment on your computer neat and tidy. Virtual environments isolate your Python/django installations on a project-by-project basis. Your changes to one website will not affect other developed websites.
(Terminal) Create a new directory djangogirls under the home directory and move into that directory:
mkdir djangogirls cd djangogirls
(Terminal) Create a virtual environment myvenv, command:
python3 -m venv myvenv
2. Use a virtual environment
(Terminal) Enter the following command (replace myvenv with the name of your virtual environment):
~/djangogirls$ source myvenv/bin/activate
When the (myvenv) prefix appears, you are already in the virtual environment.
3. Install django
django can be installed with pip in a virtual environment. Enter the following command in the terminal:
pip install django==1.8
Use a double equals sign followed by the version of django you want to install.
