javascript - ./src/App.js 模块未找到 : Can't resolve '@material-ui/data-grid' in xxx

Question

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 },
{ id: 4, lastName: 'Stark', firstName: 'Arya', age: 16 },
{ id: 5, lastName: 'Targaryen', firstName: 'Daenerys', age: null },
{ id: 6, lastName: 'Melisandre', firstName: null, age: 150 },
{ id: 7, lastName: 'Clifford', firstName: 'Ferrara', age: 44 },
{ id: 8, lastName: 'Frances', firstName: 'Rossini', age: 36 },
{ id: 9, lastName: 'Roxie', firstName: 'Harvey', age: 65 },
];

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>
  
  </div>;

  }

  export default App;

我尝试了 cmd npm install @material-ui next 或类似的东西，但它仍然没有导入网格。
请帮忙

Answer 1

数据网格不包含在 material-ui 的核心安装中。
安装数据网格:

npm install @material-ui/data-grid

导入它:

import { DataGrid } from '@material-ui/data-grid'
