我正在尝试在我的React Native应用程序中添加一个功能，以便能够创建语音注解并在我的Django后端（POST API）中发送。
使用import AudioRecorderPlayer from 'react-native-audio-recorder-player';库。
在我的组件中，我使用TouchableOpacity创建了Buttons。按钮为“开始录制”、“停止录制”和“播放音频”。
当我使用这些按钮中的任何一个来调用我的方法时，我得到以下错误：

[00:09:51] null is not an object (evaluating 'RNAudioRecorderPlayer.startPlayer')
at node_modules\react-native-audio-recorder-player\index.ts:null in AudioRecorderPlayer#startPlayer

下面是我的代码：

const startRecording = async () => {
    try {
      const path = await audioRecorderPlayer.startRecorder();
      audioRecorderPlayer.addRecordBackListener((e) => {
      this.setState({
        recordSecs: e.currentPosition,
        recordTime: this.audioRecorderPlayer.mmssss(Math.floor(e.currentPosition)),
      })
    })
      setAudioPath(path);
      console.log(path)
  } catch (error) {
    console.error(error);
  }
}

  const stopRecording = async () => {
    try {
      const path = await audioRecorderPlayer.stopRecorder();
      audioRecorderPlayer.removeRecordBackListener((e) => {
        this.setState({
          recordSecs: 0,
        })
      })
      setAudioPath(path);
      console.log(path)
    } catch (error) {
      console.error(error);
    }
  }

  const playRecording = async () => {
    try {
      await audioRecorderPlayer.startPlayer(audioPath);
    } catch (error) {
      console.error(error);
    }
  };

在我的组件之外是AudioRecordPlayer（）的示例;

const audioRecorderPlayer = new AudioRecorderPlayer();
