升级后无法使用药剂

Question

我将我的药剂版本从3.0升级到5.0。npm 命令运行良好，但当我尝试运行gulp 时，它失败了。

我给出了我所犯的错误。

我的package.json文件(应该与https://github.com/laravel/laravel/blob/master/package.json的文件相同)

{
  "private": true,
  "scripts": {
  "prod": "gulp --production",
  "dev": "gulp watch"
  },

 "devDependencies": {
 "gulp": "^3.9.1",
 "laravel-elixir": "^5.0.0",
 "bootstrap-sass": "^3.3.0"
  }
}

当运行gulp -生产时，我得到以下错误

/home/vagrant/Code/laravel/node_modules/laravel-  elixir/node_modules/gulp- cssnano/node_modules/cssnano/node_modules/postcss/lib/lazy-result.js:157

你也需要升级Node。
