Metro Bundler ready.

Loading dependency graph, done.
 BUNDLE  [android, dev] RNTester/js/RNTesterApp.android.js ▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓ 100.0% (585/585), done.

I think that this commit introduced the issue.

Actual Behavior

Loading dependency graph, done.
warning: the transform cache was reset.
error: bundling failed: Error: Unable to resolve module `metro/src/lib/bundle-modules/HMRClient` from `/Users/<user-directory>/Desktop/temp/react-native/Libraries/Utilities/HMRClient.js`: Module does not exist in the module map

Reproducible Demo

To get a demo just clone the source code from the master and execute the repro steps.

Applying e048bf1 locally fixed the issue for me.

Thanks for posting this! It looks like you may not be using the latest version of React Native, v0.53.0, released on January 2018. Can you make sure this issue can still be reproduced in the latest version?

I am going to close this, but please feel free to open a new issue if you are able to confirm that this is still a problem in v0.53.0 or newer.
