I had this issue, you can try to do:

cd ios
pod install

and then try to compile and run again

[cesargdm]

Also happened to me, deleting the app and reinstalling worked for me, may be a problem with the linking

I'm having the same error in iOS hardware:

    "react": "^16.3.0-alpha.1",
    "react-native": "0.54.2",
    "react-native-sound": "0.10.9"

I installed via react-native link

I can confirm this issue as well. Neither pod install or running link solves it.

[Irrelon]

Steps to fix:

1. Install the module as documented in the readme of this repo
2. If you deploy to iOS then cd to ios and run pod install
3. Go to your test device and DELETE the app from it if you have ever deployed it there before
4. Compile the app and run it on your device (e.g. go to xcode for ios or android studio for android) and compile and deploy to your device
5. Once a new version of the app is on your device it will work

The reason for this is pretty simple if you think about it. Whenever you install a new module that uses native code extensions the app you have previously deployed to your device will NOT contain that code so needs to be recompiled and re-deployed to the device. Simply refreshing the existing app only refreshes the JavaScript code, not any native underlying app code on the device.
