React Native: run-ios has stopped working (ReferenceError)

I've run into an issue when running the run-ios command. Prior to now, the app started up fine, but now I'm running into this screen before the app even finishes bundling.

Here's a link to the screen I'm getting: https://d17oy1vhnax1f7.cloudfront.net/items/1J3n3u1z3w2k2E160V1B/Screen%20Shot%202017-01-18%20at%2010.36.08%20AM.png?v=783d1021

Here are some of the steps I've gone through to debug the problem:

  • Reset the cache on startup with npm start --reset-cache
  • Cleared the watchman config
  • Enabled remote debugging to pause on caught exceptions*
  • Created a new branch for a previous commit that I know had worked prior to this issue (no resolution)
  • Removed and reinstalled my node_modules folder
  • Removed and reinstalled watchman through homebrew
  • Cleared npm cache
  • Upgraded react-native to 0.40.0

*This is the line where the error is catching on when inspecting in chrome:

global = DedicatedWorkerGlobalScope {console: Object, __fbBatchedBridgeConfig: Object, __DEV_

I've tried a number of solutions in a number of issues but haven't been able to come up with the right solution.

Here's some possibly relevant information:

Solution

  • Well I feel like a complete idiot, but the solution here was just to restart my computer. There must have been a leftover process running that was interfering with the way things were bundling.
