【问题描述】：
我正在尝试设置 react native 以在 android 模拟器上工作。我正在使用 Ubuntu 18.04。当我尝试使用“react-native run-android”时收到此错误消息：
BUILD FAILED in 1m 21s
28 actionable tasks: 28 executed
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.
我在我的 react native 项目中的 settings.gradle 中找到了一个答案，上面写着将“/”替换为“”。文件中唯一的内容是：rootProject.name = ‘AwesomeProject’ include ‘:app’
我已添加：
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 bashrc 结尾。
【问题讨论】：
-
你是在添加
PATH之后运行source ~/.bashrc，还是尝试打开一个新的终端运行react？ React 找不到adb二进制文件，因此要么未设置PATH，要么未安装adb。您能否验证adb是否安装在Android/Sdk/platform-tools/adb上？ -
我已经更新了 bashrc 是的。有一个文件，但没有一个名为 adb 的文件夹是的
