Question

当我尝试运行我的简单Sails.JS应用程序（包含swaggerui）时，我收到以下错误：

$ sails lift

npm install，npm uninstall sails或npm cache clear不起作用。我已经尝试过再次重新安装grunt-cli并再次使用saig-swagger ...... 有人在这里有解决方案吗？

github.com上的问题也已打开......

使用sails-swagger时，您还必须在sails应用程序的config目录中为swagger创建配置文件。此配置文件设置一个pkg变量，该变量指向sails应用程序的package.json文件。

上面的错误基本上是说无法找到属性pkg，因此招摇不起作用。

要解决此问题，请首先在config目录中创建一个名为swagger.js的文件。

然后将以下内容添加到swagger.js文件

module.exports.swagger = {
  /**
   * require() the package.json file for your Sails app.
   */
  pkg: require('../package'),
  ui: {
    url: 'http://swaggerui.balderdash.io'
  }
};

Sails.JS：TypeError：无法读取未定义的属性'pkg'
