'base64 is not a function‘错误

Question

我正在按照https://angular.io/guide/aot-compiler的说明获取一个AOT版本。

根据Bootstrap部分，您需要将您的main.ts从以下位置切换：

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

要这样做：

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

但是，在切换之后，当我运行ngc编译器时，我得到了这个错误：

Error: Command failed: C:\Windows\system32\cmd.exe /s /c "ngc -p tsconfig-aot.json"
TypeError: base64 is not a function

我知道"Base64 is not a function error in Node.JS 5.3 and below" problem，但我使用的是NodeJS v8.2.1。

尝试以下代码：

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

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