ng build --prod have javaScript heap out of memory

Question

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?

Answer 1

Which Typescript version you are using?

if it is in 2.x.x, update to 2.7.x where they have fixed.

Answer 2

I was facing same issue with ionic 3 unit testing.

npm test

was getting memory issue in above command then got it fixed with below commands--

npm install

node --max_old_space_size=8048 ./node_modules/@angular/cli/bin/ng test

It worked for me.
