无法解析来自"srcmain.jsx"的导入"react-dom/client"。该文件是否存在？

Question

解决这个问题

Failed to resolve import "react-dom/client" from "srcmain.jsx". Does the file exist?

这是我的主要。jsx文件

import React from 'react'
import ReactDOM from 'react-dom/client'
// import {render} from "react-dom";
import App from './components/App.jsx'
import './index.css'
ReactDOM.createRoot(document.getElementById('root')).render(
<React.StrictMode>
<App />
</React.StrictMode>
)

我也试过这样做

import React from 'react'
import {render} from "react-dom";
import App from './components/App.jsx'
import './index.css'

const container = document.getElementById("root");
render(
<React.StrictMode>
<App />
</React.StrictMode>,
container
);

但是这个显示空白页

如果有人能帮忙，请看看这个

我正在尝试使codependency复制项目这些是我在package .json

中的依赖项

"dependencies": {
"@fortawesome/fontawesome-svg-core": "^1.2.31",

},

Answer 1

而不是:

import App from './components/App.jsx'

写:

import App from './App';

它对我有效。

Answer 2

运行"npm "它将解决这个错误，因为当您手动安装deps时，似乎缺少了一些依赖项。
