如何在Android Studio中手动链接react-native-camera？

Question

为了澄清，我运行的是一台使用Android Studio的Windows计算机。

我正在尝试在react原生应用程序中使用react- native -camera设置二维码扫描器。

我可以毫不费力地安装库：

$ npm install react-native-camera --save

给出

我所见过的每一个在线参考资料，比如https://facebook.github.io/react-native/docs/linking-libraries-ios，似乎只有在你在Mac上为iOS编程时才会给出指导。

https://react-native-community.github.io/react-native-camera/docs/installation上的库的文档建议使用自动链接

$ react-native link react-native-camera。

我得到了：

info Linking "react-native-camera" iOS dependency
info iOS module "react-native-camera" has been successfully linked
info Linking "react-native-camera" Android dependency
info Android module "react-native-camera" has been successfully linked

当我使用$ react-native run-android在我的设备上构建它时，问题出现了，我得到了：

error React Native CLI uses autolinking for native dependencies, but the following modules are linked manually:
  - react-native-camera (to unlink run: "react-native unlink react-native-camera")
This is likely happening when upgrading React Native from below 0.60 to 0.60 or above. Going forward, you can unlink this dependency via "react-native unlink <dependency>" and it will be included in your app automatically. If a library isn't compatible with autolinking, disregard this message and notify the library maintainers.

手动链接的唯一结果是在XCode上，但是有谁可以帮助我使用Android Studio吗？我真的很感激。

看起来您使用的是新版本的react-native (0.60或更高版本)。在这种情况下，您不必自己链接库，因为支持最新的react-native的库现在可以在安装时自行链接。

您应该能够执行npm install react-native-camera --save并使其正常工作。如果您以前使用过react-native link react-native-camera，现在可能需要运行react-native unlink react-native-camera来恢复通过link命令执行的操作。您可能还需要重新安装库(先安装npm uninstall react-native-camera，再安装npm install react-native-camera --save)。如果它仍然不起作用，你可以通过manual installation of this library
