我的功能提供了一个小图像图标作为可触摸的按钮来上传或拍照，使用"react-native-image-picker": "^3.3.2"。

我收到 error: ，与此GitHub 问题Cannot read property 'launchImageLibrary' of undefined相同，但如您所见，我的代码已经按照他们的指示进行了导入。

这是我的完整代码：

import React from 'react';
import {
    StyleSheet,
    Image,
    TouchableOpacity,
    Alert
} from 'react-native';
import { launchImageLibrary } from 'react-native-image-picker';

const ImageUpload: React.FC<any> = ({}) => {

    function showMessage() {
        Alert.alert("Upload image", "Choose a option", [
            {
                text: 'Camera',
                onPress: () => openCamera(),
            },
            {
                text: 'Gallery',
                onPress: () => openLibrary()
            },
        ]);
    }

    const openLibrary = () => {

        const options = { …

var ImagePicker = require('react-native-image-picker');
call() {   
    var options = {
      title: 'Select Avatar',
      customButtons: [
        {name: 'fb', title: 'Choose Photo from Facebook'},
      ],
      storageOptions: {
        skipBackup: true,
        path: 'images'
      }
    };
      ImagePicker.showImagePicker(options, (response) => {
      console.log('Response = ', response);

      if (response.didCancel) {
        console.log('User cancelled image picker');
      }
      else if (response.error) {
        console.log('ImagePicker Error: ', response.error);
      }
      else if (response.customButton) {
        console.log('User tapped custom button: ', response.customButton);
      }
      else {
        let source = { uri: response.uri };
