Question

我正在尝试将android .apk文件下载到内部android文件系统中的downloads文件夹中。我已经尝试了许多事情，例如react-native-fs，react-native-install-apk，expo的FileSystem，目前我正在尝试使react-native-simple-download-manager工作。这是供您参考的链接https://www.npmjs.com/package/react-native-simple-download-manager。

Expo的文件系统没有引发任何错误，但由于无法在文件系统上找到.apk，因此我无法访问APK进行安装。

我不太清楚为什么，但是所有这些软件包都使用require语法而不是import。我尝试使用require并像import ReactNativeDownloadManager from 'react-native-simple-download-manager';一样正常导入包，但我不断收到这样的错误，它找不到未定义的函数下载。显然，由于我已经在以下链接https://github.com/master-atul/react-native-simple-download-manager/blob/master/index.js的ReactNativeDownloadManager内部进行了查找，因此无法正确导入。如果将鼠标悬停在导入本身上，我还将获得以下提示。

找不到模块'react-native-simple-download-manager'的声明文件。 d：/React/SpringApp/node_modules/react-native-simple-download-manager/index.js隐式具有“ any”类型。

    Could not find a declaration file for module 'react-native-simple-download-manager'. 'd:/React/SpringApp/node_modules/react-native-simple-download-manager/index.js' implicitly has an 'any' type.
  Try `npm install @types/react-native-simple-download-manager` if it exists or add a new declaration (.d.ts) file containing `declare module 'react-native-simple-download-manager';`

我确实尝试在命令行中运行它，但出现此错误。

npm ERR! code E404
npm ERR! 404 Not Found: @types/react-native-simple-download-manager@latest

如果有人可以在正确的方向上指导我解决此问题，或为我提供下载apk的更好方法，请执行！谢谢。

PS：是的，我知道它说不正确，而不是下载。这是我无法控制的已有服务。
