对照老师的，一模一样啊，不知道问题出在哪里了。。
代码如下：
import React, { Component } from ‘react’;
import ‘antd/dist/antd.css’;
import { Input, Button, List } from ‘antd’;
import store from './store/index.js’
import { getInputChangeAction, getAddItemAction, getDeleteItemAction } from ‘./store/actionCreators5.8’

class TodoList extends Component {

constructor(props) {
super(props);
this.state = store.getState();
this.handleInputChange = this.handleInputChange.bind(this);
this.handleStoreChange = this.handleStoreChange.bind(this);
this.handleBtnClick = this.handleBtnClick.bind(this);
store.subscribe(this.handleStoreChange); //store的内容只要改变，括号中函数就执行。
}

render() {
return (
<div style={{marginTop: ‘10px’, marginLeft: ‘10px’}}>

<List
style={{marginTop: ‘10px’, width: ‘300px’}}
bordered
dataSource={this.state.list}
renderItem={(item, index) => (
<List.Item onClick={this.handleItemDelete.bind(this, index)}>
{item}
</List.Item>
)}
/>

)
}

handleInputChange(e) {
const action = getInputChangeAction(e.target.value);
store.dispatch(action);
}

handleStoreChange() {
this.setState(store.getState())
}

handleBtnClick() {
const action = getAddItemAction();
store.dispatch(action);
}

handleItemDelete(index) {
const action = getDeleteItemAction(index);
store.dispatch(action);
}

}

export default TodoList;
