React-Redux @connect语法错误

Question

我是使用React和Redux的新手，正在构建一个简单的todos应用程序。我正在命令行中使用create-react-app工具编写应用程序。

问题

我去了其他博客和帖子，其他人提到我缺少一个npm插件来转换装饰器“ transform-decorators-
legacy”，将其与Babel一起添加到我的依赖项中，但仍然收到相同的错误。

Syntax error: Unexpected token (9:0)

   7 | import './App.css';
   8 |
>  9 | @connect((store) => {
     | ^
  10 |   return {
  11 |     user: store.user.user
  12 |   }

我的密码

import React, { Component } from 'react';
import { connect } from 'react-redux';

import Todos from './components/Todos';
import Todo from './components/Todo';

import './App.css';

@connect((store) => {
  return {
    user: store.user.user
  }
})
class App extends Component {
  constructor(){
    super()
    this.state = {
      name: 'Brad',
      todos: [
        {
          id: '001',
          name: 'Take out trash',
          completed: false
        },
        {
          id: '002',
          name: 'Meeting with boss',
          completed: false
        },
        {
          id: '003',
          name: 'Go out to dinner',
          completed: false
        }
      ]
    }
  }
  render() {
    return (
      <div className="App">
        <h1>Hello</h1>
        <Todos name={this.state.name} todos={this.state.todos}/>
        <Todo/>
      </div>
    );
  }
}

export default App;

我的依赖

package.json

{
  "name": "react-redux-project",
  "version": "0.1.0",

尝试这样：

const stateMap = (state) => {
    console.log('state', state);
    return {
        //something from state
    };
};

export default connect(stateMap)(App);
