Hi! I am Neal Owen, I’m 71, retired, and MM looked lie a neat project to play with . . . if only I can get it to work!!!

I am looking at MM on a laptop running Raspbian as the OS. I was following the Manual Install and when I entered ‘npm install’ I received: ‘bash: npm: command not found’. What am I missing? If I run ‘node --version’ I get v10.19.0
