title: Command "react-native" can not run after installed react-native-drawer
body: <p>I inited React native project by:</p>
  
  <p>react-native init MyShop
  In MyShop folder, I install "<a href="https://github.com/root-two/react-native-drawer" rel="nofollow noreferrer">react-native-drawer</a>":</p>
  
  <p>npm install --save react-native-drawer
  After install, I run project by:</p>
  
  <p>react-native run-android
  And get error "Command run-android unrecognized. Make sure that you have run npm install and that you are inside a react-native project."
  I checked react-native by command line</p>
  
  <p>react-native -v
  And get info:</p>
  
  <p>react-native-cli: 2.0.1
  react-native: n/a - not inside a React Native project directory
  It seems react-native lib has been removed after installed react-native-drawer.
  My npm version:</p>
  
  <p>E:\2.Projects\My\MyShop>npm -v
  5.0.4
  My node version:</p>
  
  <p>E:\2.Projects\My\MyShop>node -v
  v8.1.2
  Please help me re-procedure and fix it. Thank you!</p>
