Something is wrong with my React installation/ Node as a whole [duplicate]

Question

I stopped practicing react for a few months and recently when I picked it up again, I was not able to even create a react app properly. There is a dependency conflict.

These are the errors whenever I ran the "npx create-react-app appname" command:

npm error code ERESOLVE
npm error ERESOLVE unable to resolve dependency tree

I've tried:

• Downgrading react
• Completely reinstalling react
• Repairing node

This is also interfering with my mongodb installation What else can I do?

I think it's because React has just updated to v19 last week and testing-library/react hasn't updated their dependency requirements yet.

In 2024, I would suggest creating a new React App using Vite. Try running this

npm create vite@latest
