ng build --prod have javaScript heap out of memory

I am facing the below issue while using ng build --prod.

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

Tried increasing the size limit by using https://github.com/endel/increase-memory-limit but it is still failing to build. Do i need to change anywhere in the node_modules?
