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

[alwx]

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] Building Dependency Graph (5403ms)
[node-haste] Encountered an error while persisting cache:

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.

I have same issues. Happened when i switched to react-native 0.28 from 0.26.3.

[alwx]

Downgrading doesn't help. I believe it is not a 0.28-specific issue.

[phil-allcock]

I have tried to reclone the project and still hitting the same error

i wrapped json as a string in js file as a quickfix and parsing it in runtime.

[alwx]

@zaynyatyi it is, of course, bad solution for production releases.
I spent the day working on it, still have no idea why it happens.

[Bhullnatik]

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.

[zaynyatyi]

@alwx it is, but currently it's a blocker and it's just a quick solution while there is no fix
@Bhullnatik that worked, thanks.

[alwx]

@Bhullnatik it works, thanks!

How did you downgraded this package? You've installed it like npm i -E babylon@6.8.1 ?

[zaynyatyi]

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

[ColCh]

No way for me. Even with this command:

cd node_modules/react-native; npm install babylon@6.8.1; cd ../../;

@ColCh what's your npm list babylon says in root of your project?

[ColCh]

@zaynyatyi

$ 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@6.8.1 

[zaynyatyi]

looks like issues fixed, you can upgrade babylon to latest (6.8.3) on
react-native

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", ( 8b803c6 ), and according to semver, 6.8.3 will be installed, if you run npm install react-native

We're still experiencing this regardless of the upgrade to react-native@0.36.0

[rasom]

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

babel/babel#4795

[cogwheel]

Downgrading babel no longer fixes this starting around react native 0.43.0. It breaks the build in another way (I can't recall at the moment).

Might be related: #12590 (comment)

[tobowers]

i'm having the same problem with an expo app with babylon 6.18.0

I've opened a metro bug for this here facebook/metro#111
