Environment

Environment:
OS: macOS Sierra 10.12.5
Node: 7.10.0
Yarn: 0.24.5
npm: 4.2.0
Watchman: 4.7.0
Xcode: Xcode 8.3.3 Build version 8E3004b
Android Studio: 2.3 AI-162.4069837

Packages: (wanted => installed)
react: 16.0.0 => 16.0.0
react-native: 0.49.0 => 0.49.0

Steps to Reproduce

prerequisite: Have a react-native app with version 0.49.0

1. Install and use a package with dynamic imports statements such as moment.js
2. Run the app
3. Witness red screen of death notifying of TransformError

Expected Behavior

I expected the project to build and run as it did for the RN version I was using before (0.48.4).

Actual Behavior

I got an error saying that a require() must have a string literal argument. Even though the responsible for this error was located in the source code of a dependency (Moment.js)
require('./locale/' + name);
