Native modules for sensors not available. Did react-native link run successfully?

I followed the first steps of the React Native tutorial here:

https://facebook.github.io/react-native/docs/getting-started.html

Then I want to read information from the device sensors.

For that I also followed this tutorial:

https://medium.com/react-native-training/using-sensors-in-react-native-b194d0ad9167

and ended up with this code (just copy/pasted from there):

// Reference:// https://medium.com/react-native-training/using-sensors-in-react-native-b194d0ad9167// https://react-native-sensors.github.ioimport React, { Component } from 'react';import {  StyleSheet,  Text,  View} from 'react-native';import { Accelerometer } from "react-native-sensors";const Value = ({name, value}) => (<View style={styles.valueContainer}><Text style={styles.valueName}>{name}:</Text><Text style={styles.valueValue}>{new String(value).substr(0, 8)}</Text></View>)export default class App extends Component {  constructor(props) {    super(props);    new Accelerometer({      updateInterval: 400 // defaults to 100ms    })      .then(observable => {        observable.subscribe(({x,y,z}) => this.setState({x,y,z}));      })      .catch(error => {        console.log("The sensor is not available");      });    this.state = {x: 0, y: 0, z: 0};  }  render() {    return (<View style={styles.container}><Text style={styles.headline}>          Accelerometer values</Text><Value name="x" value={this.state.x} /><Value name="y" value={this.state.y} /><Value name="z" value={this.state.z} /></View>    );  }}const styles = StyleSheet.create({  container: {    flex: 1,    justifyContent: 'center',    alignItems: 'center',    backgroundColor: '#F5FCFF',  },  headline: {    fontSize: 30,    textAlign: 'center',    margin: 10,  },  valueContainer: {    flexDirection: 'row',    flexWrap: 'wrap',  },  valueValue: {    width: 200,    fontSize: 20  },  valueName: {    width: 50,    fontSize: 20,    fontWeight: 'bold'  },  instructions: {    textAlign: 'center',    color: '#333333',    marginBottom: 5,  },});

Here is the full repository you can download and try right away:

$ git clone https://github.com/napolev/react-native-app$ cd react-native-app$ npm i$ expo start

My problem is that after I do: $ expo start I get the following error:

Native modules for sensors not available. Did react-native link run successfully?

as you can see on the following image:

Any idea about how can I make this work?

Thanks!
