Angular 6，Firebase 3.9.0-在node_modules / firebase / auth.js中未定义全局

Question

因此，我正在使用Angular 6使用AngularFire2构建Web应用程序，并且在加载应用程序时出现以下错误：

auth.js:255 Uncaught ReferenceError: global is not defined
    at Object../node_modules/firebase/auth.js (auth.js:255)
    at __webpack_require__ (bootstrap:81)
    at Object../node_modules/firebase/firebase-browser.js (firebase-browser.js:11)
    at __webpack_require__ (bootstrap:81)
    at Object../src/app/core/auth.service.ts (auth.guard.ts:18)
    at __webpack_require__ (bootstrap:81)

    at __webpack_require__ (bootstrap:81)
    at Object../src/app/app.module.ts (app.component.ts:9)
    at __webpack_require__ (bootstrap:81)

我不确定这是否与我拥有的angular版本有关，但我有一个使用Angular 4使用这两个库的ionic应用程序，并且运行良好。

以下是相关的软件包：

  "@angular/animations": "^6.0.1",
    "@angular/common": "^6.0.1",
    "@angular/compiler": "^6.0.1",
    "@angular/core": "^6.0.1",
    "@angular/forms": "^6.0.1",
    "@angular/http": "^6.0.1",
    "@angular/platform-browser": "^6.0.1",
    "@angular/platform-browser-dynamic": "^6.0.1",
    "@angular/platform-server": "^6.0.1",
    "@angular/pwa": "^0.6.1",
    "@angular/router": "^6.0.1",
    "@angular/service-worker": "^6.0.1",
    "@nguniversal/module-map-ngfactory-loader": "^6.0.0",
    "angularfire2": "^4.0.0-rc.1",
    "core-js": "^2.5.4",
    "firebase": "^3.9.0"

我在这里使用的AngularFire和Firebase版本缺少某些内容吗？

作为临时的技巧，请转到pollyfill.ts文件（您可能会在应用程序的src文件夹中找到它）并粘贴(window as any).global = window;在文件末尾。
