如何在React Typescript应用程序中导入react-admin？

npm install react-admin

import * as React from 'react';
import { Admin, Resource } from 'react-admin';
import { PostList, PostEdit, PostCreate } from './posts';
import { UserList } from './users';
import { Dashboard } from './dashboard';
import jsonServerProvider from 'ra-data-json-server';

import './App.css';

const dataProvider = jsonServerProvider('https://jsonplaceholder.typicode.com');

const App = () => (
    <Admin dashboard={Dashboard} dataProvider={dataProvider}>
        <Resource name="posts" list={PostList} edit={PostEdit} create={PostCreate} />
        <Resource name="users" list={UserList} />
    </Admin>
);

export default App;
