• AsyncStorage in React Native is not global.

  Solution:

  • If you want to use AsyncStorage locally, you can use asteroid#3.0.0-alpha.

• Error with node-haste persisting cache
  Error stack trace:

  [node-haste] Encountered an error while persisting cache:
  > Error: Couldn't find preset "es2015" relative to directory "[project_path]/node_modules/asteroid"
  

  and, after install babel-preset-es2015

  [node-haste] Encountered an error while persisting cache:
  > Error: Couldn't find preset "stage-0" relative to directory  "[project_path]/node_modules/asteroid"
  

  Fix:

  • install babel-preset-es2015 and babel-preset-stage-0

• Error with EventEmitter: Asteroid 2.0 Babel Preset Problem on React Native #90

  undefined is not an object (evaluating 'exports.EventEmitter')
  on asteroid/node_modules/wolfy87-eventemitter/EventEmitter.js
  

  Possible causes:
  It seems to be a problem when different version of wolfy87-eventemitter in ddp.js and asteroid are included.

  Fix:
  If you have this issue, try to install wolfy87-eventemitter as a dependency.

Thank you for the information!
I got a little different error:

TransformError: [project_path]/node_modules/asteroid/lib/asteroid.js: Couldn't find preset "es2015" relative to directory "[project_path]/node_modules/asteroid"

After I installed babel-preset-es2015 and babel-preset-stage-0 and restart the app, still the same error.
Any suggestions?
Thanks!

I also tried 3.0.0-alpha branch and clean the cache, but still the same error.

Hi @tongdu99,

Did you have a .babelrc file in your project?
