Make sure you have an Android emulator running or a device connected and have
set up your Android development environment.
Go to https://facebook.github.io/react-native/docs/getting-started.html
and check the Android tab for setup instructions.

请确保您已安装 sdk 并正确设置 sdk 和 android platform-tools 的路径。

检查你的 .bashrc 文件或者如果在 mac 上检查 .bashprofile。

或者您还可以在每次运行该应用程序时执行此操作。

在项目文件夹中运行以下命令。(如果您遵循官方 RN 文档，这些路径将有效)。

导出 ANDROID_HOME=~/Library/Android/sdk

导出路径=${PATH}:${ANDROID_HOME}/tools

export PATH=${PATH}:${ANDROID_HOME}/platform-tools
