【问题描述】：
我构建了一个 react+flask 应用程序，我想使用 Material-UI 我测试了按钮，它可以工作，我需要一个数据网格，一个表格，我得到了这个错误：
./src/App.js
Module not found: Can't resolve '@material-ui/data-grid' in 'C:\spvreact\react-flask-app\src'
在控制台中我得到了这个：
Uncaught Error: Cannot find module '@material-ui/data-grid'

这是代码：
import React, { useEffect } from 'react';
import logo from './logo.svg';
import './App.css';
import Button from '@material-ui/core/Button';
import { DataGrid } from '@material-ui/data-grid';
function App() {
const columns = [
{ field: 'id', headerName: 'ID', width: 70 },
{ field: 'firstName', headerName: 'First name', width: 130 },
{ field: 'lastName', headerName: 'Last name', width: 130 },
{
field: 'age',
headerName: 'Age',
type: 'number',
width: 90,
},
{
field: 'fullName',
headerName: 'Full name',
description: 'This column has a value getter and is not sortable.',
sortable: false,
width: 160,
valueGetter: (params) =>
`${params.getValue('firstName') || ''} ${
params.getValue('lastName') || ''
}`,
},
];
const rows = [
{ id: 1, lastName: 'Snow', firstName: 'Jon', age: 35 },
{ id: 2, lastName: 'Lannister', firstName: 'Cersei', age: 42 },
{ id: 3, lastName: 'Lannister', firstName: 'Jaime', age: 45 },

];
useEffect(() => {
fetch('http://127.0.0.1:5000/formular',{
headers : {
'Content-Type': 'application/json',
'Accept': 'application/json'
}
}).then(response =>
response.json().then(data =>{
console.log(data);
})
);
},[]);

</div>;
}
export default App;我尝试在 cmd npm install @material-ui next 或类似的东西中，但它仍然没有导入网格。
请帮忙

试过重新安装包吗？您是否正确安装了
'@material-ui/data-grid'包？ -
谢谢它的工作，我想如果我下载@material-ui它会下载所有组件。
