您的JSON中缺少逗号（第22行）：

"styles": [
     "app/core/preloader/preloader.scss",
     "styles.scss" <----
     "../node_modules/bootstrap/dist/css/bootstrap.min.css"
 ],

有效的JSON：

 {
  "project": {
    "version": "1.0.0-beta.24",
    "name": "ki-angular2-spa-form0"
  },
  "apps": [
    {
      "root": "src",
      "outDir": "dist",
      "assets": [
        "assets",
        "favicon.ico"
      ],
      "index": "index.html",
      "main": "main.ts",
      "test": "test.ts",
      "tsconfig": "tsconfig.json",
      "prefix": "app",
      "mobile": false,
      "styles": [
         "app/core/preloader/preloader.scss",
         "styles.scss",
        "../node_modules/bootstrap/dist/css/bootstrap.min.css"
      ],
      "scripts": [


        "app/core/preloader/preloader.ts",
        "vendor.ts"
      ],
      "environments": {
        "source": "environments/environment.ts",
        "dev": "environments/environment.ts",
        "prod": "environments/environment.prod.ts"
      }
    }
  ],
  "addons": [],
  "packages": [],
  "e2e": {
    "protractor": {
      "config": "./protractor.conf.js"
    }
  },
  "test": {
    "karma": {
      "config": "./karma.conf.js"
    }
  },
  "defaults": {
    "styleExt": "css",
    "prefixInterfaces": false,
    "inline": {
      "style": false,
      "template": false
    },
    "spec": {
      "class": false,
      "component": true,
      "directive": true,
      "module": false,
      "pipe": true,
      "service": true
    }
  }
}

您可以使用JSONLint验证您的JSON并查找错误。

你的angular-cli.json有一个json错误，你忘记了一个逗号：

  "styles": [
    "app/core/preloader/preloader.scss",
    "styles.scss"
    "../node_modules/bootstrap/dist/css/bootstrap.min.css"
  ],

应该是

 "styles": [
    "app/core/preloader/preloader.scss",
    "styles.scss",
    "../node_modules/bootstrap/dist/css/bootstrap.min.css"
  ]

为了确保您的json有效，您可以将其放入json validator;
