Angular 7 FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

Question

My project is big. In the last build I added big chunk of new functionality. Building process giving me this error log.

Changing --max-old-space-size=4096 not working for me.

Can you try --max-old-space-size=8192 with the below prod command

node --max-old-space-size=8192 ./node_modules/@angular/cli/bin/ng build --aot=true --optimization=true --source-map=false
