Response-native: the `run-android` command is not recognized. May be caused by npm installation

Question

Recently, I started getting this problem when I install the package responsible for the reaction (for example:) react-navigationin my project, a whole bunch of packages are removed (including reacting, reacting - I think).

And then, when I try to run the " run-android" command , it says that it does not recognize.

I recently updated to the latest npmand react-native-cli. Is this 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-navigation: 1.0.0-beta.11

Following are the steps to recreate:

• Step 1 - Create a project.

• Step 2 - Run the "run-android" command (This works).

• Step 3 - Install “respond to native-navigation” to the project.

Notice in the image above. Seems like all the other packages are removed from the project.<br/><br/>

• 4 - "run-android". (, )

class HomeScreen extends Component {
  static navigationOptions = {
    title: 'Welcome',

  render() {
    const { navigate } = this.props.navigation;
    return (
      <Button
        title="Go to Jane profile"
        onPress={() =>
          navigate('Profile', { name: 'Jane' })

class ProfileScreen extends Component{
  static navigationOptions = {
    title: 'Jane',
  };
  render() {
    return (null);
  }
}

const NavTest= StackNavigator({
  Home: { screen: HomeScreen },
  Profile: { screen: ProfileScreen },
});

AppRegistry.registerComponent('NavTest', () => NavTest);
