Question

I'm trying to create a new react app, but I can't seem to do it. I have searched everywhere and done everything I could that can be done nothing is working. I have deleted node, npm, and npx two times and downloaded again, and then restarting my computer like 100 times but nothing works:

Need to install the following packages:

Ok to proceed? (y) 

You are running `create-react-app` 4.0.3, which is behind the latest release (5.0.0).

We no longer support global installation of Create React App.

Please remove any global installs with one of the following commands:
- npm uninstall -g create-react-app
- yarn global remove create-react-app

The latest instructions for creating a new app can be found here:

How can I fix this?

Answer 1

First, remove the package. If you have installed create-react package using npm then use

- npm uninstall -g create-react-app

or if yarn

- yarn global remove create-react-app

Then you can create a project:

npx create-react-app my-app

Answer 2

The problem seems to be that of an inappropriate installation. The go-to way to fix this would be to ensure a proper uninstall of node and npm . Please follow the steps mentioned here . Once properly uninstalled, head over to install node and proceed with the re-installation.
