我正在尝试编译一个location-saver依赖项，react-native-vector-icons我无法建立。
经过多次尝试，构建失败。这是日志：
react-native run-android
JS server already running.
Building and installing the app on the device (cd android && ./gradlew installDebug)...
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring project ':app'.

Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have

我什至更改了react-native-vector node_module的build.grade中的支持库版本。
需要一个项目的帮助，这是本机新手。
