如何在Angular 4中将样式导出为css文件

Question

我是Angular 4中的新手，我想将我的样式导出为css文件。 当我提供或构建项目时，它会创建一个style.bundle.js文件并将css'添加为html样式元素。但我想导出样式表文件并使用link元素加载它。

My Angular-cli.json：

{
  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
  "project": {
    "name": "ares"
  },
  "apps": [
    {
      "name":"desktop",
      "root": "src",
      "outDir": "dist/desktop",
      "assets": [
        "assets",
        "favicon.ico",
        "views/desktop"
      ],
      "index": "index.html",
      "main": "main.ts",
      "polyfills": "polyfills.ts",
      "test": "test.ts",
      "tsconfig": "tsconfig.app.json",
      "testTsconfig": "tsconfig.spec.json",
      "prefix": "app",
      "styles": [
        "../node_modules/materialize-css/dist/css/materialize.css",
        "../node_modules/font-awesome/css/font-awesome.css",
        "assets/desktop/css/styles.scss",
        "views/desktop/trader/first/assets/css/theme.scss"
      ],
      "scripts": [
        "../node_modules/jquery/dist/jquery.js",
        "../node_modules/hammerjs/hammer.js",
        "../node_modules/materialize-css/dist/js/materialize.js"
      ],
      "environmentSource": "environments/environment.ts",
      "environments": {
        "dev": "environments/environment.ts",
        "prod": "environments/environment.prod.ts"
      }
    }
  ],
  "e2e": {
    "protractor": {
      "config": "./protractor.conf.js"
    }
  },
  "lint": [
    {
      "project": "src/tsconfig.app.json",
      "exclude": "**/node_modules/**"
    },
    {
      "project": "src/tsconfig.spec.json",
      "exclude": "**/node_modules/**"
    },
    {
      "project": "e2e/tsconfig.e2e.json",
      "exclude": "**/node_modules/**"
    }
  ],
  "test": {
    "karma": {
      "config": "./karma.conf.js"
    }
  },
  "defaults": {
    "styleExt": "scss",
    "component": {}
  }
}

当您运行ng build或ng serve时，它总是创建一个像styles.bundles.js这样的包，只是为了节省开发构建的时间。另一方面，如果你ng build --prod，它将产生styles.bundle.css。

如果您希望为您的开发版构建styles.bundle.css，则只需添加--extract-css标记，例如ng serve --extract-css。
