直接上代码
以下是login.jsx的代码

import React from 'react';
import ReactDOM from 'react-dom';
import {
    render
} from 'react-dom';
import {
    Form,
    Icon,
    Input,
    Button,
    Checkbox
} from 'antd';

const FormItem = Form.Item;

class LoginForm extends React.Component {
    // constructor(props) {
    //     super(props);
    //     this.loginSubmit = this.loginSubmit.bind(this);
    // };
    loginSubmit = (e) => {
        e.preventDefault();
        this.props.form.validateFields((err, values) => {
            if (!err) {
                console.log('Received values of form: ', values);
            }else{

            }
        });
    }
    render() {
        const {
            getFieldDecorator
        } = this.props.form;
        return (
            

                
                    {
                        getFieldDecorator('sss', {
                                rules: [{ required: true, message: 'Please input your username!' }],
                            }
                        )
                        (
                            } placeholder="Username" />
                        )
                    }
                
                
                    {getFieldDecorator('password', {
                        rules: [{ required: true, message: 'Please input your Password!' }],
                    })(
                        } type="password" placeholder="Password" />
                    )}
                
                
                    {getFieldDecorator('remember', {
                        valuePropName: 'checked',
                        initialValue: true,
                    })(
                        Remember me
                    )}
                    Forgot password
                    

                        
                            Log in
                        
                        Or register now!
                    
                    
                
            
        );
    }
}
const Login = Form.create()(LoginForm);
export default Login;

保存后浏览器打开直接报错，我查了下react和antd 都是这么写的，具体报错如下：

求大神指教
