React Native无法运行stacktrace

Question

我正在尝试建立一个测试项目并在Mac（osx 10.12）上与React Native一起运行。如果我运行：

react-native run-android --stacktrace

我收到以下错误：

error: unknown option '--stacktrace'

我已经安装了：

• Node watcher
• flow
• Java JDK
• Android SDK
• React to nativeCLI
• Genymotion

当我运行命令时，模拟器正在运行。

谁能告诉我为什么会这样吗？提前谢谢了。

编辑 运行后，gradlew installDebug --stacktrace我得到以下响应：

Deprecated Gradle features were used in this build, making it incompatible with Gradle 5.0.
Use '--warning-mode all' to show the individual deprecation warnings.

该--stacktrace建议不是react-native run- android命令输出的，它来自它运行的命令之一。使用--stacktrace选项运行它的方法如下。进一步阅读以获取解释。

cd android && ./gradlew installDebug --stacktrace

react-native run-android``cd android && ./gradlew installDebug正如您在以下输出的以下行中看到的那样，它实际运行react-native run-android

Running /Users/upside/Library/Android/sdk/platform-tools/adb -s 0111474880b8a726 reverse tcp:8081 tcp:8081
Building and installing the app on the device (cd android && ./gradlew installDebug)...

因此，如果要使用该--stacktrace选项运行，则需要运行cd android && ./gradlew installDebug --stacktrace

解决问题后，应重新使用，react-native run-android因为脚本可能还会运行很多命令。
