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>

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

它抱怨说它找不到我的Android SDK，但我已经在我的环境变量中的

Android\u HOME

下指出了它。出于某种原因，我不相信这个堆栈跟踪。我可能做错了什么？

通过在目录

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

中创建一个名为

local.properties

的文件来解决问题，该文件的内容只有一行：

sdk.dir=C:\\Users\\mnxe\\AppData\\local\\Android\\sdk

顺便说一句，能够用HTML/CSS/JavaScript开发UI真的很酷。

这个变量不可靠。相反，

在local.properties文件中用sdk.dir定义位置

或者，证明你可以

echo

终端中的变量alecho ANDROID\u HOME只是给了ANDROID\u HOME。@cricket\u 007我该怎么做？我应该将此文件添加到哪个文件夹？

local.properties

。。。不是申请。如果回声不起作用，那么错误就不存在了。设置环境变量后，需要重新启动CMD。
