Error trying to install Router Flux

I came across a very annoying error when trying to install Router Flux in the folder of my app6 some suggestion:

Note: I've already installed two libraries:

  

npm install --save eslint-config-rallycoding npm install --save

     

react-native-router-flux

code: index.android.js

import React, { Component } from 'react';
import { AppRegistry } from 'react-native';
import { Router, Scene } from 'react-native-router-flux';

import Principal from './src/components/Principal';
import SobreJogo from './src/components/SobreJogo';
import OutrosJogos from './src/components/OutrosJogos';

export default class app extends Component {
  render() {
    return (
      <Router sceneStyle={{ paddingTop: 50 }}>
        <Scene key='principal' component={Principal} initil title="Cara ou coroa" />
        <Scene key='sobrejogo' component={SobreJogo} title="Sobre o Jogo" />
        <Scene key='outrosjogos' component={OutrosJogos} title="Outros Jogos" />
      </Router>
    );
  }
}

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

MAIN

import React, { Component } from 'react';
import {
  StyleSheet,
  View,
  Image,
  TouchableHighlight
} from 'react-native';

import { Actions } from 'react-native-router-flux';

const logo = require('../imgs/logo.png');
const btnJogar = require('../imgs/botao_jogar.png');
const btnSobreJogo = require('../imgs/sobre_jogo.png');
const btnOutrosJogos = require('../imgs/outros_jogos.png');

export default class Principal extends Component {
  render() {
    return (
      <View style={styles.cenaPrincipal}>

        <View style={styles.apresentacaoJogo}>
          <Image source={logo} />
          <Image source={btnJogar} />
        </View>

        <View style={styles.rodape}>
          <TouchableHighlight
            onPress={() => { Actions.sobrejogo(); }}
          >
            <Image source={btnSobreJogo} />
          </TouchableHighlight>

          <TouchableHighlight
            onPress={() => { Actions.outrosjogos(); }}
          >
            <Image source={btnOutrosJogos} />
          </TouchableHighlight>
        </View>

      </View>
    );
  }
}

const styles = StyleSheet.create({
  cenaPrincipal: {
    flex: 1,
    backgroundColor: '#61BD8C'
  },
  apresentacaoJogo: {
    flex: 10,
    justifyContent: 'center',
    alignItems: 'center'
  },
  rodape: {
    flex: 1,
    flexDirection: 'row',
    justifyContent: 'space-between'
  }
});
