Each Linux distro is a bit different, so for this guide, I am going to focus on Ubuntu.

  2. Mu requires Python3. You can check and see if you have Python3 installed by typing python3 --version If nothing is displayed type sudo apt install python3to install Python3.
  3. You also need pip3 installed type pip3 --version If it shows nothing you need to install pip3 by typing sudo apt install python3-pip
  4. Finally to install Mu type pip3 install mu_editor
  5. You can now run Mu from the command line by typing Mu

Now that you have Mu installed you can go and develop in Python3, MicroPython for micro:bit or even CircuitPython for the Adafruit Circuit Playground Express.
