react-native: Command `run-android` unrecognized. Maybe caused by npm install
问题 Recently I started getting this issue, when I install a react-native package (eg: react-navigation ) into my project, a whole bunch of packages are been removed (including react, react-native i think). And then when i try to run command " run-android ", it says it doesn't recognize. I recently updated to the latest npm and react-native-cli . Is it something wrong with " npm install "? or react-native ? node version: 8.1.2 <br/> react-native-cli: 2.0.1 <br/> react-native: 0.45.1 <br/> react
