TypeError: null is not an object (evaluating '_nativeInterface.default.getPhotos') Cameraroll react native community

Question

我在尝试从 cameroll 获取照片时遇到此错误 "TypeError: null is not an object (evaluating '_nativeInterface.default.getPhotos')"。我确保已获得 android 和 ios 的所有许可。为 ios 安装必要的 pods 并且库也被链接。在 git 和 Whosebug 上尝试了一堆建议，但仍然没有成功。

import {
  View,
  Text,
  StyleSheet,
  TouchableOpacity,
  ActivityIndicator,
  Image,
  FlatList,
  Dimensions,
} from 'react-native';
import CameraRoll from '@react-native-community/cameraroll';

class AvatarBioScreen extends PureComponent {
  state = {
    images: [],
    loading: false,
    selected: null,
    hasNextPage: false,
    endCursor: '',
    firstQuery: true,
  };

  componentDidMount() {
    this._getPhotos();
  }

  _getPhotos = async after => {
    if (this.state.firstQuery) {
      this.setState({loading: true});
    }

    const res = await CameraRoll.getPhotos({
      first: 20,
      after,
    });

    this.setState({
      images: [...this.state.images, ...res.edges],
      loading: false,
      hasNextPage: res.page_info.has_next_page,
      endCursor: res.page_info.end_cursor,
      firstQuery: false,
    });

    console.log('====================================');
    console.log('res', res);

    console.log('====================================');
  };
}```

你的代码很好。确保你运行 pod install 因为模块找不到这个组件时会出现这个错误
