He probado esta solución: https://github.com/angular/angular-cli/issues/5618#issuecomment-450151214

es decir

package.json

"scripts": {
        "ng": "ng",
        "ng-high-memory": "node --max_old_space_size=8000 ./node_modules/@angular/cli/bin/ng",// here
        "start": "ng serve",
        "build:prod": "ng build --configuration=prod",
    },

Después de eso

npm run ng-high-memory --build --prod

Pero dice

¿Entonces cómo puedo ejecutar este comando correctamente?

Nota: Utilizo la última versión de Angular, es decir, "@angular/core": "^8.2.14", y "@angular/cli": "^8.3.19",

Respuesta #1

Esto funciona para mí en noviembre de 2019

He actualizado a la última versión de Angular de la siguiente manera: ng update @angular/cli@^8 @angular/core@^8

Entonces

package.json

"scripts": {
    "ng-high-memory": "node --max_old_space_size=8000 ./node_modules/@angular/cli/bin/ng build --configuration=prod",
}

Después de eso:

npm run ng-high-memory

Actualiza la versión de Node.js a v12 o a una versión superior a la que estás utilizando actualmente.
