标签： java android reactjs gradle

我只是关注官方网站上的指南：https://facebook.github.io/react-native/docs/getting-started.html

命令： 

C:\Users\mnxe\Documents\Android Projects\AwesomeProject>react-native run-android

完整错误：

BUILD FAILED

Total time: 3.626 secs
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
set up your Android development environment:
https://facebook.github.io/react-native/docs/android-setup.html

C:\Users\mnxe\Documents\Android Projects\AwesomeProject>

重要部分： 

java.lang.RuntimeException: SDK location not found. Define location with sdk.dir
     in the local.properties file or with an ANDROID_HOME environment variable.

它抱怨它无法找到我的Android SDK，但我已经在ANDROID_HOME下的环境变量中指出了它。出于某种原因，我不相信这种堆栈跟踪。我能做错什么？

1 个答案:

答案 0 :(得分：1)

通过使用单行内容local.properties在目录C:\Users\mnxe\Documents\Android Projects\AwesomeProject\android中创建名为sdk.dir = C:\\Users\\mnxe\\AppData\\Local\\Android\\sdk的文件解决了问题。

顺便说一句，能够使用HTML / CSS / JavaScript开发UI非常酷。
