ReactNative运行报错Command `run-android` unrecognized. Make sure that you have run `npm install` and that you are inside a react-native project.

新建的React Native项目，运行react-native run-android时报错

Command `run-android` unrecognized. Make sure that you have run `npm install` and that you are inside a react-native project.

在项目目录下运行(不能是sudo su（运行sudo命令给su命令提权，运行su命令）下)

yarn add react-native-cli

再运行react-native run-android即可
