'Form' 未定义 react/jsx-no-undef

Question

hi with app react下方我必须管理一个表单才能验证登录到页面，参数是电子邮件和密码，但是当我执行代码时，打印了以下错误，错误：行33：'form'不是定义的react/jsx-no-undef

JavaScript代码：

import React, { Component } from 'react';
import { Button, FormGroup, FormControl, ControlLabel } from "react-bootstrap";
import logo from './logo.svg';
import './Home.css';
class Home extends Component {
  constructor(props) {
    super(props);
    this.state = {
      email: "",
      password: ""
    };
  }
  validateForm() {
    return this.state.email.length > 0 && this.state.password.length > 0;
  }
  handleChange = event => {
    this.setState({
      [event.target.id]: event.target.value
    });
  }
  handleSubmit = event => {
    event.preventDefault();
  }
  render() {
    return (
      <div className="Login">
        <Form onSubmit={this.handleSubmit}>
          <Form.Group controlId="email" bsSize="large">
            <Form.Control
              autoFocus
              type="email"
              value={this.state.email}
              onChange={this.handleChange}
            />
          </Form.Group>
          <Form.Group controlId="password" bsSize="large">
            <Form.Control
              value={this.state.password}
              onChange={this.handleChange}
              type="password"
            />
          </Form.Group>
          <Button
            block
            bsSize="large"
            disabled={!this.validateForm()}
            type="submit"
          >
            Login
              </Button>
        </Form>
      </div>
    );
  }
}
export default Home;

似乎您忘了导入Form，只需添加：

import { Form, Button, FormGroup, FormControl, ControlLabel } from "react-bootstrap";
