- Steps:
1) It’s a good idea to keep all your virtualenvs in one place, for example 
in .virtualenvs/ in your home directory. Create it if it doesn’t exist yet:
$ mkdir ~/.virtualenvs

2) Install: 
$ apt-get install python3-venv
$ sudo apt install virtualenv

3) Now create a new virtualenv by running:
$ python3 -m venv ~/.virtualenvs/djangodev


4) The final step in setting up your virtualenv is to activate it:
$ source ~/.virtualenvs/djangodev/bin/activate

5) Before running the test suite, install its dependencies by first cd-ing into the Django tests/ directory and then running:
$ pip install -r requirements/py3.txt
