Erro com bootstrap

Estou com um problema no meu projeto,

nele não existe o arquivo angular.json e sim angular-cli.json, dentro desse arquivo existe a tag styles e dentro dela fiz a alteração pedida:

{
  "project": {
    "version": "1.0.0-beta.28.3",
    "name": "alurapic"
  },
  "apps": [
    {
      "root": "src",
      "outDir": "dist",
      "assets": [
        "assets",
        "favicon.ico"
      ],
      "index": "index.html",
      "main": "main.ts",
      "polyfills": "polyfills.ts",
      "test": "test.ts",
      "tsconfig": "tsconfig.json",
      "prefix": "app",
      "styles": [
        "styles.css",
        "./node_modules/bootstrap/dist/css/bootstrap.min.css"
      ],
      "scripts": [],
      "environments": {
        "source": "environments/environment.ts",
        "dev": "environments/environment.ts",
        "prod": "environments/environment.prod.ts"
      }
    }
  ],
  "e2e": {
    "protractor": {
      "config": "./protractor.conf.js"
    }
  },
  "lint": [
    {
      "files": "src/**/*.ts",
      "project": "src/tsconfig.json"
    },
    {
      "files": "e2e/**/*.ts",
      "project": "e2e/tsconfig.json"
    }
  ],
  "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
    }
  }
}

porém quando vou reiniciar o server ele me retorna o seguinte erro:

ERROR in multi ./src/styles.css ./src//bootstrap/dist/css/bootstrap.min.css Module not found: Error: Can't resolve 'D:\DADOS\N66104\Desktop\projeto\AngularAngular 1\alurapic\src\node_modules\bootstrap\dist\css\bootstrap.min.css' in 'D: \DADOS\N66104\Desktop\projeto\Angular\Angular 1\alurapic' @ multi ./src/styles.css ./src//bootstrap/dist/css/bootstrap.min.css webpack: Failed to compile.

Entendi do erro que ele está buscando na pasta errada então alterei para

"styles": [ "styles.css", "../node_modules/bootstrap/dist/css/bootstrap.min.css" ],

que me retornou o seguinte erro:

Se alguém puder me ajudar.
