react-native: Error building project ("transforming index.android.js took longer than 301 seconds.")

Hello, everybody. Everything was absolutely fine, but now I can’t build my project anymore and every time I try I see the following error:

… [10:14:28 PM] <END> Building Dependency Graph (5403ms) [node-haste] Encountered an error while persisting cache: Error: TimeoutError: transforming /Users/alwxndr/Documents/Dev/_2016/rn-app/index.android.js took longer than 301 seconds. You can adjust timeout via the ‘transformTimeoutInterval’ option at /Users/alwxndr/Documents/Dev/_2016/rn-app/node_modules/react-native/packager/react-packager/src/JSTransformer/index.js:95:28 at tryCallOne (/Users/alwxndr/Documents/Dev/_2016/rn-app/node_modules/promise/lib/core.js:37:12) at /Users/alwxndr/Documents/Dev/_2016/rn-app/node_modules/promise/lib/core.js:123:15 at flush (/Users/alwxndr/Documents/Dev/_2016/rn-app/node_modules/asap/raw.js:50:29) at _combinedTickCallback (node.js:370:9) at process._tickCallback (node.js:401:11) /Users/alwxndr/Documents/Dev/_2016/rn-app/node_modules/promise/lib/done.js:10 throw err; ^

More importantly, even if I do git checkout <sha of some old commit> in my project, I can’t make it buildable. Maybe it is some cache error or something like that, but, of course, I am not sure. Brief googling didn’t help.

react-native bundle --platform ios --dev false --entry-file index.ios.js --bundle-output main.jsbundle --assets-dest ./ios doesn’t work too.

It seems to be coming from the last version of babel/babylon. Downgrading it to 6.8.1 instead of 6.8.2 fixes the issue for me.

This error can appear again because of babel-plugin-transform-es2015-block-scoping@6.18.0. You can fix this by downgrading it to babel-plugin-transform-es2015-block-scoping@6.15.0

@ColCh just go to node_modules/react-native and do npm i babylon@6.8.1 there

Yeah, I noticed that version bumb.

$ npm list babylon
Foo@0.0.1 /Users/someuser/Foo
├─┬ babel-core@6.10.4
│ └── babylon@6.8.3 
└─┬ react-native@0.28.0
  └── babylon@6.8.3

Checked on old build which failed with babylon@6.8.1 now builds succesfully… Nice! 👍

RN depends on "babylon": "^6.8.2", ( https://github.com/facebook/react-native/commit/8b803c6143732915a6a390a2e1495e9355372aef ), and according to semver, 6.8.3 will be installed, if you run npm install react-native
