Configuring virtual environments
Virtual environments are used to create separate development environments for different projects with different requirements. For example, you can specify which version of Python and which libraries/modules you want to be installed in a particular virtual environment.
As an example, to create a virtual environment in the PythonAnywhere bash, we could run the following:
mkvirtualenv -p python3.8 <environment name>
Here, we have specified that we use Python 3.8 in virtualenv. Whatever packages we install will always be there and independent of other virtualenvs.
Now, in the PythonAnywhere bash, run the following:
mkvirtualenv -p python3.8 moviereviewsenv
We will see the name of virtualenv in Bash, which means we are in the Virtual Environment (VE) (Figure 12.10).

Back in our virtualenv, we need to install django and pillow (as we did in development). So...
