Activating the virtualenv

Activating the Virtualenv

The init script we ran in the last step created a bunch of code to help get us started but it also created a virtual environment within our directory. If you haven’t used virtualenv before, you can find out more here but the bottom line is that they allow you have a self-contained, isolated environment to run Python and install arbitrary packages without polluting your system Python.

To take advantage of the virtual environment that was created, you have to activate it within your shell. The generated README file provides all of this information but we are calling it out here because it is important. To activate your virtualenv:

source .env/bin/activate

Now that the virtual environment is activated, you can safely install the required python modules.

pip install --upgrade -r requirements.txt
