I am using Angular CLI. Please check my CLI info

@angular/cli: 1.2.1
node: 6.10.0
os: win32 x64
@angular/animations: 4.1.1
@angular/common: 4.0.0
@angular/compiler: 4.0.0
@angular/compiler-cli: 4.0.0
@angular/core: 4.0.0

@angular/http: 4.0.0
@angular/platform-browser: 4.0.0
@angular/platform-browser-dynamic: 4.0.0
@angular/router: 4.1.1

When I use ng serve --aot I am getting the following error.

for angular 7, I increased the maximum memory allocated for budgets in angular.json file.

"budgets": [
                {
                  "type": "initial",
                  "maximumWarning": "2mb",
                  "maximumError": "11mb"
                }
]

then ran the following command: node --max_old_space_size=10500 'node_modules/@angular/cli/bin/ng' build --prod

in your case you should try to run this: node --max_old_space_size=10500 'node_modules/@angular/cli/bin/ng' serve --aot

This issue comes if the angular app will become bigger in size to compile. Please increase your node ram memory that will solve the issue. (Default node ram memory is 1600mb, increase it to around 3200)
