How to do it...

Once you have your prerequisites installed, create a directory where all your Django projects will be stored, for example, virtualenvs under your home directory. Perform the following steps after creating the directory:

1. Go to the newly created directory and create a virtual environment that uses the shared system site packages:

$ cd ~/virtualenvs
$ mkdir myproject_env
$ cd myproject_env
$ virtualenv --system-site-packages .
Using base prefix '/usr/local'
New python executable in ./bin/python3.6
Also creating executable in ./bin/python
Installing setuptools, pip, wheel...done.

1. To use your newly created virtual environment, you need to execute the activation script in your current shell. This can be done with the following command:

$ source bin/activate

1. Depending on the shell you are using, the source command may not be available. Another way to source a file is with the following command, which has the same result (note the space between the dot and bin):

$ . bin/activate

1. You will see that the prompt of the command-line tool gets a prefix of the project name, as follows:

(myproject_env)$

1. To get out of the virtual environment, type the following command:

(myproject_env)$ deactivate
