What is the right way to install Node.js and Python?

Install Node.js through fnm and Python through uv. Both are free version managers that let each project use the version it needs, without the permission errors and broken installs that come from older methods. Most AI coding tools and web frameworks need Node.js; data and AI scripts usually need Python.
