[Ionic v4] ionic build --prod timeout

[marcelgoya]

Description: I'm getting a timeout every time I try to compile the app with the prod flag. The node daemon seems to be sleeping as well since there's no cpu usage.

Steps to Reproduce: Run ionic build --prod --engine browser or ionic cordova build android --prod

Output:

 ionic build --prod --engine browser --verbose

  ionic:cli-utils CLI global options: { _: [ 'build' ], help: null, h: null, verbose: true, quiet: null, interactive: true, color: true, confirm: null, json: null, prod: true, engine: 'browser', project: null, '--': [] } +153ms

What is logging those snapdragon:compiler/snapdragon:parser statements? I've never seen that before.

Production build working for me: ionic cordova build android --device --prod --aot and ionic cordova run android --device --prod --aot Both OK.

@dwieeb Alright, I did some thorough inspection and basically what happens is that the script creates around a dozen node sub-processes and all of them go into some sort of sleep mode after around 30 seconds. I've also tried compiling under windows and it works fine there. I've also tested one of the app starter templates and the problem exists there as well, so it's not something code related. Btw, I'm running Ubuntu on Windows, so I don't know if this problem occurs on vanilla linux as well.

I'm interested in your remark! I have the same statements (hundreds of them) when I start my app since Ionic CLI v4

@CheetahDev I've found it's normal for Ionic 1 apps since we turned on verbose logging. (But not Ionic 4)

[CheetahDev]

Thanks for the quick reply @dwieeb It has however a side effet: we have a eslint task checking our code in real time. Verbose logging causes here tons of outputs (it outputs eslint relative stuff for minutes until we shutdown the process).

Will try to record this.

@dwieeb here it is https://imgur.com/a/8O0rcys

Runing the same command without --verbose starts the app without issue. But with the verbose flag it is impossible.

[imhoffd]

--verbose will set the DEBUG environment variable to *, so subprocesses like eslint also have verbose logging (because most things use this module: https://www.npmjs.com/package/debug)

Maybe instead, use DEBUG="ionic:*" ionic serve

But anyway, please create a new issue! We're hijacking this one.

@marcelgoya Any updates?
