undefined is not an object (evaluating 'NativeModules.VideoManager.ScaleAspectFill') about react-native-video

Hi @wheycool! Which version of react-native are you using? And react-native-video? Thanks for the full example!

[wheycool]

Downloaded react-native-video from you today, so the latest I presume. React Native is what NPM is currently providing: v0.1.3

[brentvatne]

React Native version should be 0.4.4 😄

[wheycool]

Sorry, I was mistaken. I just checked out the package.json within the react-native node, and it's 0.4.4.

[wheycool]

Fixed it! I just started from scratch with the NPM install. I must have been doing something wrong the first time. Sorry for wasting your time – and thanks for getting back to me! :)

[brentvatne]

no problem @wheycool, glad you resolved it!

Hey, I am running into this issue too. Still trying to debug it, but re-installing didn't work

[brentvatne]

@markburns - react native version? reinstall might require a npm cache clean and a rm -rf node_modules/react-native-video

[markburns]

Just tried that, same problem. Also clean, build, and reset the content and settings on the iOS simulator.

react-native-video 0.4.1
react-native 0.4.4

@markburns - probably a sign that it's not linking correctly, try going through these steps again: https://github.com/brentvatne/react-native-video#add-it-to-your-project

[markburns]

Yeah that was it, thanks.

WDYT about having something like:

if(!NativeModules.VideoManager){
  throw("NativeModules.VideoManager is undefined - ensure you are linking the library correctly " + 
        "https://github.com/brentvatne/react-native-video/issues/40");
}

as a fail fast?

I imagine a lot of people who are familiar with JS will be attracted to React Native, and if this is/becomes the defacto video library then it might keep people like me (less familiar with Xcode/native) from making too much noise in the issues.

@markburns - I like that! can you submit a PR?
