Ionic 2 allocation failed when built with --prod

Hey everyone,

I’m currently migrating my IONIC v2Beta11 project (which has always built with no problems) to IONIC v3.0.1.

This is the first time I try to build it with --prod flag and I keep getting “Allocation failed - process out of memory” error.

I’ve tried increasing the maximum memory allocation to 8GB but I still get the same error after a while of constant memory increasement on NodeJs process.

I did it by changing node_modules/.bin/ionic-app-scripts.cmd to:

@IF EXIST “%~dp0\node.exe” (
"%~dp0\node.exe --max_old_space_size=8192 " “%~dp0…@ionic\app-scripts\bin\ionic-app-scripts.js” %*
) ELSE (
@SETLOCAL
@SET PATHEXT=%PATHEXT:;.JS;=;%
node --max_old_space_size=4096 “%~dp0…@ionic\app-scripts\bin\ionic-app-scripts.js” %*
)

Note that ionic build android, ionic run android and ionic serve all works fine.

I’ve read a topic somewhere that says once the projects gets bigger, it stops working.
Is it a known issue?

Could someone help me on this?
