I am trying to create a Weather App. It works fine on web but does not work on my phone. I am using the expo online snack editor to test this. screenshot of the error:

All of my code is

I also tested it in the "iOS" tab of the snack editor & it has the same error as on my phone.

P.S. to get the exact result shown in the screenshot inside of snack:

1. Go to the Open Weather API website
2. Sign up for an account
3. Get your API key from the email that was sent to you
4. Go into functions/fetchWeather.js in snack editor
5. On line 2, replace where it says "redacted" with your api key that you got from that email.

CodePudding user response：

It's happening because your code has a string outside from a Text component. Line 45 has a {' '} and it needs to be wrapped for the Text component from react-native. Your code will be something this:

// Rest of the code above

render() {
  return (
    <View>
      <RequestLocation />
      <Text>Weather App</Text>
      <Text>Weather for your location today:</Text>
      <Weather
        morn={Math.round(this.state.temp['morn'])}
        day={Math.round(this.state.temp['day'])}
        eve={Math.round(this.state.temp['eve'])}
        night={Math.round(this.state.temp['night'])}
        max={Math.round(this.state.temp['max'])}
        min={Math.round(this.state.temp['min'])}
      />
      <Text>{' '}</Text>
      {/* Showing weather with passed values from this file to the main weather component
      (code de-cluttering) */}
    </View>
  );
}
