我正在尝试设置本机反应以在Android模拟器上工作。我正在使用 Ubuntu 18.04。当我尝试使用"反应本机运行-android"时，我收到此错误消息：
BUILD FAILED in 1m 21s

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:

此外，它还说：
A problem was found with the configuration of task ‘:app:installDebug’. File ‘/home/william/Android/platform-tools/adb’ specified for property ‘adbExe’ does not exist.
我找到了一个答案，说在我的 set .gradle 中将"/"替换为"在我的反应本机项目中。然而，文件中唯一的问题是：rootProject.name = 'AwesomeProject' 包括 '：app'
我补充了：
export PATH="$HOME/bin:$PATH"
export ANDROID_HOME=$HOME/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools
到我的巴什克的尽头。
对我来说，解决方案是创建android/local.properties文件并在磁盘上指定SDK路径 sdk.dir=/username/Android/Sdk
