FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory - webpack sample Angular 2

Question

I am facing an issue in webpack sample while getting webpack build:

FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

package.json

"build": "rimraf dist && node_modules\\.bin\\webpack --config config/webpack.prod.js --progress --profile --bail",

Thanks @Kasiriveni . I already used it at ngc.cmd, but still am facing this. — Kbvin, May 22 '17 at 09:21
Please update to the latest version of npm npm install -g npm@latest — Kasiriveni, May 23 '17 at 07:22
In the webpack.config file try commenting or removing devtool:'source-map' — Raphael, May 22 '18 at 13:47

Every single time when i got the same error i managed to solve the issue using the --max_old_space_size option.

My guess would be that either --max_old_space_size=4096 is not enough (just use a higher value) or that the option is not applied in the right place.

I would try:

"build": "rimraf dist && node --max-old-space-size=8192 node_modules\\.bin\\webpack --config config/webpack.prod.js --progress --profile --bail"
