React Native无法运行stacktrace [英] React Native cannot run stacktrace

问题描述

我正在尝试在Mac上使用React Native启动测试项目（osx 10.12）。如果我运行：

react-native run-android --stacktrace

我收到以下错误：

错误：未知选项'--stacktrace'

我已经安装：

• Node Watchman


• 流程


• Java JDK


• Android SDK


• React Native CLI


• Genymotion

• Node Watchman
• Flow
• Java JDK
• Android SDK

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？非常感谢提前。

Can anyone tell me why this is happening? Many thanks in advance.

推荐答案

- stacktrace 建议不是'由 react-native run-android 命令输出，它来自它运行的一个命令。以下是使用 - stacktrace 选项运行它的方法。进一步阅读以获得解释。

The --stacktrace suggestion isn't output by the react-native run-android command, it comes from one of the commands it runs. Here's how to run it with the --stacktrace option. Read further for an explanation.

cd android && ./gradlew installDebug --stacktrace

react-native run-android 实际上运行 cd android&& ./gradlew installDebug 正如您在 react-native run-android

react-native run-android actually runs cd android && ./gradlew installDebug as you can see in the following lines outputted by 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)...

所以，如果你想用 - stacktrace 选项运行，你需要运行 cd android&& ./gradlew installDebug --stacktrace

So, if you want to run with the --stacktrace option, you'll need to run cd android && ./gradlew installDebug --stacktrace

一旦你发现问题，你应该回到使用 react-native run-android 因为脚本可能会运行更多的命令。

Once you've figured out your problem, you should go back to using react-native run-android as the script probably runs a lot more commands as well.
