npm run dev not working with webpack/babel conflict - node.js

Question

I am trying to run npm run dev for a Vue project but I keep getting the following output:
npm ERR! code ERESOLVE
npm ERR! ERESOLVE could not resolve
npm ERR!

I have no idea what to do, I have tried uninstalling vue-cli and tried re-installing it (I'm not sure if this messed up my packages). Is there a way to cleanly delete everything and start fresh? If anyone can help that would be much appreciated!
Update:
I tried starting a new project with vue init webpack frontend in a new folder and tried installing axios and am getting the following error

I recently updated my version of node (v19.1.0) and npm (v8.19.3), could that be an issue? It generally seems like I am getting a bunch of conflicts every time I try to install new packages. Is there a way to just start clean?

Answer 1

Probably one of your packages is outdated, according to the error. I guess it's the babel loader.
Method 1 Upgrading or Updating your packages might solve the dependency error.
Method 2 Try running npm install --force or npm install --legacy-peer-deps. It should work.
