尝试在 nextjs 中使用 React 语音识别模块时出现错误

Question

我正在尝试在我的 next.js 网站中实现语音识别。我下载并尝试使用此链接中的相同代码，但出现此错误：

ReferenceError: regeneratorRuntime is not defined

    at Object.<anonymous> (C:\Users\simer\Downloads\Talkhappi\client\node_modules\react-speech-recognition\lib\SpeechRecognition.js:16:50)

我不确定为什么会发生这种情况，因为我按照上面链接的 npm 下载网站的说明进行操作。这是我的代码：

import SpeechRecognition, { useSpeechRecognition } from 'react-speech-recognition'

const Product = () => {
  const {
    transcript,
    listening,
    resetTranscript,
    browserSupportsSpeechRecognition
  } = useSpeechRecognition();

  // Handle browser support error
  if (!browserSupportsSpeechRecognition) {
    return <span>Browser doesn't support speech recognition.</span>;
  }

  return (
      <div style={styles.container}>
          <div style={styles.speechTitle}>Talk to us, tell us about your day...</div>
          <div style={styles.speechBox}>

          </div>
          <button onClick={() => console.log('hello')}>Hello</button>
          <p>Microphone: {listening ? 'on' : 'off'}</p>
          <button onClick={SpeechRecognition.startListening}>Start</button>
          <button onClick={SpeechRecognition.stopListening}>Stop</button>
          <button onClick={resetTranscript}>Reset</button>
          <p>{transcript}</p>
      </div>

  );
}

export default Product

它位于文档底部 - 故障排除下方。 https://www.npmjs.com/package/react-speech-recognition

regeneratorRuntime is not defined

如果您在使用此库时看到错误 regeneratorRuntime is not defined，则需要确保您的网络应用程序已安装regenerator-runtime：

• npm i --save regenerator-runtime

• 如果您使用 NextJS，请将其放在文件的顶部_app.js： import 'regenerator-runtime/runtime'。对于任何其他框架，请将其放在您的顶部index.js file
