  1. Try pip install tornado.
  2. If any permission errors are coming in terminal then try sudo pip install tornado.

In general, when instructions say:

To install package123 run pip install package123

99% of the time, it's assuming that the package is being installed in a Python virtual environment (via virtualenv or venv). With that being said, you should install Tornado in a virtual environment and avoid sudo pip install tornado. Nothing bad will happen if you do use sudo other than pollution of your system packages with 3rd party modules.
