Angular 5 错误 (Angular CLI) - 无法运行 ng build --prod

Question

角度错误信息

我就是想不通这个。 如果我通过 ng serve 和 ng build 在本地运行它，它工作正常。 但是，当我运行 ng build --prod 时，它失败并显示“./scr/main.ts 中的错误。找不到模块：错误无法解析 './app/app.module.ngFactory in ...ClientApp\\”源代码”

我已经提供了我的 main.ts/.angular-cli.json/package.json/app.module.ts。

我错过了什么？？

//main.ts
import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

import { AppModule } from './app/app.module';
import { environment } from './environments/environment';

export function getBaseUrl() {
  return document.getElementsByTagName('base')[0].href;
}

const facilitys = [
  { provide: 'BASE_URL', useFactory: getBaseUrl, deps: [] }
];

if (environment.production) {
  enableProdMode();
}

platformBrowserDynamic(facilitys).bootstrapModule(AppModule)
  .catch(err => console.log(err));

Answer 1

所以我找到了解决办法。 从我的应用程序中切出多个部分后，我终于得到了一个更好的错误消息。 我不再使用的较低级别的组件有一个简单的错误，但 VS 没有告诉我。 一旦我删除了该组件及其引用，错误就会消失。 angular CLI 和 wepack 的错误消息如此糟糕，这有点令人沮丧。 我仍然不明白为什么常规 ng build 有效，但 ng build --prod 失败了。 我认为 ng build 也会失败。 无论如何，问题已解决

Answer 2

我删除了：

“../node_modules/bootstrap/dist/css/bootstrap.css.map”

来自 angular-cli.json 并且它起作用了。
