Angular-cli: AoT - Allocation failed - JavaScript heap out of memory Even with Beta 20-4

[naveedahmed1]

When I compile my project which uses lazyloading using latest version of angular cli (ng build --prod --aot) it fails with "JavaScript heap out of memory " error..

I am using:

angular-cli: 1.0.0-beta.20-4
node: 6.9.1
os: win32 x64

Below is the log:

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

You can try running the process with more memory. I've had to do similar for my app w/ ng serve.

"node --max-old-space-size=X <path to ng> serve"

"node --max-old-space-size=4076 ~/.yarn-config/global/node_modules/angular-cli/bin/ng serve"
