为什么在呈现部分会出现这个解析错误？

Question

请帮帮我，我不明白怎么回事。我得到了这段代码，我有以下错误：

语法错误:意料之外的标记，预期的";“它指向呈现后的第一个卷曲括号。

这是代码

import Clarifai from 'clarifai'
import Navigation from './components/Navigation/navigation';
import FaceRecognition from './components/FaceRecognition/facerecognition';
import Logo from './components/Logo/logo';
import ImageLinkForm from './components/ImageLinkForm/imagelinkform';
import Rank from './components/Rank/rank';
import './App.css';
import  'tachyons'
import Particles from 'react-particles-js';




const app = new Clarifai.App({
 apiKey: 'fec62103a7704ea8b8ae7f951dc0b823'
});


const particlesOptions = {
    particles: {
        number: {
          value: 70,
          density: {
            enable: true,
            value_area: 800
          }
        }
    }
};

class App extends Component {
  constructor() {
    super();
    this.state = {
      input: '',
      imageUrl: '',
      box:{}
    }
  }
};
  calculateFaceLocation = (data) => {
      const clarifaiFace = data.output[0].data.regions[0].region_info.bounding_box;
      const image = document.getElementById('inputimage');
      const width = Number(image.width);
      const height = Number(image.height);
      console.log(width,height);
    };

  onInputChange = (event) => {
    this.setState({input: event.target.value});
  };

  onButtonSubmit = () => {
    this.setState({imageUrl: this.state.input});
    app.models
    .predict(
      Clarifai.FACE_DETECT_MODEL, 
      this.state.input)
    .then(response => this.calculateFaceLocation(response))
    .catch (err => console.log(err));
  
    
  render() {
    return (
      <div className="App">
        <Particles className='particles'
          params={particlesOptions}
        />,
        <Navigation />,
        <Logo />,
        <Rank />,
        <ImageLinkForm 
        onInputChange={this.onInputChange} 
        onButtonSubmit={this.onButtonSubmit}
        />,
        <FaceRecognition imageUrl={this.state.imageUrl} />
      </div>
    );
  }
export default App;

老实说，我不知道是怎么回事。我已经查过几次了，但我想这个错误只是逃避了。谢谢你们时间的安排。

Answer 1

onButtonSubmit丢失了}

onButtonSubmit = () => {
    this.setState({imageUrl: this.state.input});
    app.models
    .predict(
      Clarifai.FACE_DETECT_MODEL, 
      this.state.input)
    .then(response => this.calculateFaceLocation(response))
    .catch (err => console.log(err));
}; // here it is (should be :))

在您的代码中，我已经清理、格式化和修复了缺失的"}“。
