Question

我完全按照此处（https://github.com/Elyx0/react-native-document-picker/issues/94?fbclid=IwAR2Ke7ejhPYaJcT0bS7jTZHbZvXM570C7aHQQRAvHQz56C9qzvf3W1R5SkA）的说明进行操作，但是它不起作用。我收到此错误：

RNDocumentPicker: Native module is not available, make sure you have finished the installation process and rebuilt your app

当我在下面的代码中添加DocumentPicker时，出现TypeError：无法读取已定义的属性“ show”。

import { DocumentPicker, DocumentPickerUtil } from 'react-native-document-picker';

// iPhone/Android
DocumentPicker.show({
      filetype: [DocumentPickerUtil.images()],
    },(error,res) => {
      // Android
      console.log(
         res.uri,
         res.type, // mime type
         res.fileName,
         res.fileSize
      );
    });

我已经删除了node_modules并运行npm install，但是仍然出现此错误。

请问您是在哪个安装，npm 还是yarn，安装没有完成。尝试重做 yarn add react-native-document-picker --save 或 npm install react-native-document-picker --save。
