angular-cli是注入css文件thar在angular-cli.json中没有提到

Question

执行ng-serve时我意识到angular-cli正在注入我不需要的许多css，js文件？如何控制角度cls和css注射？

angular-cli.json config

{
  "project": {
    "version": "2.7.0",
    "name": "cip_front"
  },
  "apps": [
    {
      "root": "src",

      "main": "main.ts",
      "test": "test.ts",
      "tsconfig": "tsconfig.json",
      "prefix": "app",

      ],

        "prod": "environments/environment.prod.ts"
      }
    }
  ],
  "addons": [

  "packages": [

      "template": false
    },
    "spec": {
      "class": false,
      "component": true,
      "directive": true,
      "module": false,
      "pipe": true,
      "service": true
    }
  }
}

注入但未提及的文件示例是ng2-smart-table

的scss样式
