react-native run-android;找不到SDK位置，但它存在于路径中

Question

根据react-native docs，我安装了Android 8.0 (Oreo)和其他说明。唯一的区别是我在.bashrc中定义了路径varibales而不是.bash-profile。当我想运行我的反应本机应用程序时，我面对Build failed with an exception.

日志如下所示：

sudo react-native run-android
Starting JS server...
Building and installing the app on the device (cd android && ./gradlew installDebug)...
Starting a Gradle Daemon, 1 incompatible and 1 stopped Daemons could not be reused, use --status for details

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':app'.
> SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

为我建造的项目不包含local.properties。但我已经在路径中有ANDROID_HOME了。

$ printenv | grep Android
ANDROID_HOME=/home/amir/Android/Sdk
PATH=/home/amir/Android/Sdk/tools:/home/amir/Android/Sdk/tools/bin:/home/amir/Android/Sdk/platform-tools:/home/amir/Android/Sdk/emulator

正如您所提到的，默认情况下local.properties不存在，您应该将其添加到项目中。

1. 转到您的React原生项目 - > Android
2. 创建一个local.properties文件
3. 打开文件
4. 粘贴您的Android SDK路径，如下所示

   in Windows sdk.dir =    C:\\Users\\USERNAME\\AppData\\Local\\Android\\sdk
   in macOS sdk.dir = /Users/USERNAME/Library/Android/sdk
   in linux sdk.dir = /home/USERNAME/Android/Sdk

用您的用户名替换USERNAME

现在，在您的终端中运行react-native run-android。
