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.

只需确保,您已经安装了sdk并正确设置了sdk和android platform-tools的路径.

检查.bashrc文件或在mac上检查.bashprofile.

或者另外,每当您运行应用程序时,您都可以这样做.

在项目文件夹中运行以下命令.(如果您遵循官方RN文档,这些路径将起作用).

export ANDROID_HOME =〜/ Library/Android/sdk

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

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