Always make sure that your Operating System (OS) supports these commands. They all have to be executed from an elevated terminal (i.e. as an administrator). The terminal must also support Unix commands.

OS used for this demonstration: Ubuntu 20.04.1 LTS

Or Try Jupyter Notebook From The Browser
Languages supported: Python, Ruby, R, C++, Julia, Scheme, and more.

If you host your Notebooks on GitHub, you could create your own environment using Binder.
