react native 的 gradle 升级

Question

自从我在 Android Studio 中升级了 Gradle 组件后，我就无法编译我的 React Native 应用程序。 这是错误消息：

error React Native CLI uses autolinking for native dependencies, but the following modules are 
linked manually: 
  - react-native-gesture-handler (to unlink run: "react-native unlink react-native-gesture-handler")
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.

如何升级应用中的 Gradle 设置以适应新的 Gradle 功能？

React-native 版本 > 0.6，有些依赖会自动链接，我们不需要使用 react-native 链接依赖，但有些不兼容自动链接，像这样：

error React Native CLI uses autolinking for native dependencies, but the following modules are linked manually:
  - react-native-vector-icons (to unlink run: "react-native unlink react-native-vector-icons")
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.

到目前为止，解决此问题的最佳方法是返回低于 0.6 的 react-native 版本并重新安装。
