Installing Rich

00:00 Installing Rich, you can start using Rich very quickly. As always, when starting a new project or investigation, it’s best to create a virtual environment first, to avoid polluting your system’s Python installation, you can install Rich solely for use with the Python REPL, but in addition, you can also add support for Jupyter Notebooks at the same time.

00:21 So that’s the installation. You’ll see here the commands vary slightly between platforms. Here’s how to create and activate a virtual environment and then install Rich on Mac or Linux.
