What steps will reproduce the bug?

firstly i installed the recommendation version (as indicated in this issue) few times, and i cant see the placeholder of installed folder in my file system, but commands that i write after works, so i decided that i did it, but unfortunatelly it works not so as it have to work and started everything with mistake after i write next command: npm install -g yo generator-code, and output was
that i cant access to the mkdir file, i cant pin here the issue, cause i have screenshot, after it one person recommended me to installed another version of node file 12. 16.2 pkg, what i have done. and after it tried to write this command again and now i have next mistake:
npm ERR! Unexpected end of JSON input while parsing near '...:"^24.0.13","@types/n'
so... first question is how to uninstall all files that connected with node, cause i just cant understand how to decide this problem by usual way, and i dont have enough information about same problems and i dont know who or what can fix that...
so i have few versions of node files and dont know where in file system they are, and want to delete them and after it reinstall the node file, how can i did it? what command i should write in console to uninstall all files that was installed few times, and different versions? i will hope for your aswer

How often does it reproduce? Is there a required condition?

Hi. This seems unlikely to be a bug in Node.js core and might be more appropriate to discuss in one of these venues:

• Node.js help repo
• StackOverflow
• #node.js channel on libera.chat
• Node.js Slack Community (register at nodeslackers.com)
