any advice?

Answer 1

I had a similar problem, and it was due to the npm version. To resolve it, I had to uninstall all versions of Node and reinstall them. Sure! Here are the steps to uninstall Node.js and npm, including clearing the cache, on Windows:

1. Clear the npm cache:

   
      npm cache clean --force
   
   

2. Uninstall Node.js and npm:
   • Open the Control Panel by searching for it in the Start menu.
   • Go to "Programs and Features" and find Node.js in the list.
   • Select Node.js and click "Uninstall".
3. Remove residual folders:
   • Check and remove the following folders if they exist:

     
          C:\Program Files\nodejs
     
          C:\Program Files (x86)\nodejs
     
          C:\Users\{YourUsername}\AppData\Roaming\npm
     
          C:\Users\{YourUsername}\AppData\Roaming\npm-cache
     
          C:\Users\{YourUsername}\.npmrc
     
          C:\Users\{YourUsername}\AppData\Local\Temp\npm-*
     
     

4. Check environment variables:
   • Ensure there are no references to Node.js or npm in the PATH environment variable.
5. Restart your computer to apply the changes.

These steps should help you completely remove Node.js and npm from your Windows system.
