npm install no longer works but did an hour ago - node.js

Question

Can someone please help me understand what is going on here, this loaded fine an hour ago, but now it won't, I've removed the node modules and run npm cache clear --force, but still nothing. This is the error I'm getting. I'm certain it is something really really simple, I am completely new to javascript, so it's likely to be more obvious than you think.

Is there anyone that is familiar with this please, people are suggesting that I install python2.7 and other libraries that are in the error message. I can't read javascript, I'm learning it, but I know this is neither an issue with python2.7 or "node-gyp" as neither of these were installed when I had node running fine. This really is a newbie issue, there must be a simple fix for this.
