'base64 is not a function' error with ngc

Question

I'm following instructions from https://angular.io/guide/aot-compiler to get an AOT build.

As per the Bootstrap section, you need to switch your main.ts from this:

import { AppModule } from './app.module';
platformBrowserDynamic().bootstrapModule(AppModule);

to this:

import '../aot/App/app.module.ngfactory';
platformBrowserDynamic().bootstrapModule(AppModuleNgFactory);

But, after switching, when i run the ngc compiler, I get this error:

Error: Command failed: C:\Windows\system32\cmd.exe /s /c "ngc -p tsconfig-aot.json"

I know about the "Base64 is not a function error in Node.JS 5.3 and below" problem, but I'm using NodeJS v8.2.1.

Try following code:

import { enableProdMode } from '@angular/core';
import { platformBrowser }  from '@angular/platform-browser';
import { AppModuleNgFactory } from './aot/app/app.module.ngfactory';

enableProdMode();
platformBrowser().bootstrapModuleFactory(AppModuleNgFactory);
