Hey there and thank you for using React Native!

React Native, as you've probably heard, is getting really popular and truth is we're getting a bit overwhelmed by the activity surrounding it. There are just too many issues for us to manage properly.

Do the checklist before filing an issue:

• Is this something you can debug and fix? Send a pull request! Bug fixes and documentation fixes are welcome.
• Have a usage question? Ask your question on StackOverflow. We use StackOverflow for usage question and GitHub for bugs.
• Have an idea for a feature? Post the feature request on Product Pains. It has a voting system to surface the important issues. GitHub issues should only be used for bugs.

None of the above, create a bug report

Make sure to add all the information needed to understand the bug so that someone can help. If the info is missing we'll add the 'Needs more information' label and close the issue until there is enough information.

• Provide a minimal code snippet / rnplay example that reproduces the bug.
• Provide screenshots where appropriate
• What's the version of React Native you're using?
• Does this occur on iOS, Android or both?
• Are you using Mac, Linux or Windows?

This is an issue with your .babelrc file (99%). I think that's a good question for stack-overflow.

Hey @yechenfeng and thanks for posting this! @Kureev tells me this issue looks like a question that would be best asked on StackOverflow. StackOverflow is amazing for Q&A: it has a reputation system, voting, the ability to mark a question as answered. Because of the reputation system it is likely the community will see and answer your question there. This also helps us use the GitHub bug tracker for bugs only. Will close this as this is really a question that should be asked on SO.
