我正在尝试在我的服务器上运行我的新反应项目

Question

Every time run my project:

import React from 'react';
import ReactDom from 'react-dom'; 

import App from './App.js '


ReactDom.render(<App />, document.querySelector('#root'));

it keeps bringing back this error Failed to compile.

I've also reinstalled react-dom

but it Doesn't work.

Answer 1

You can try two things :
First, replace ./App.js by only App
Second, I don't know if a space can fail your import but it looks like you have one on your import.

Answer 2

Are you sure './App.js' is the right path of the App component? Because it is not being found on this path.
