javascript - Sails.JS:TypeError:无法读取未定义的属性 'pkg'

Question

尝试运行我的简单 Sails.JS 应用程序(包含 swaggerui)时，出现以下错误:

$ sails lift

npm install、npm uninstall sails 或 npm cache clear 不起作用。我已经尝试过重新安装 grunt-cli 并再次 sails-swagger ...这里有人有解决方案吗？

关于 github.com 的问题也开了……

Answer 1

使用 sails-swagger 时，您还必须在 sails 应用程序的配置目录中为 swagger 创建一个配置文件。此配置文件设置一个指向您的 sails 应用程序的 package.json 文件的 pkg 变量。

上面的错误基本上是说找不到属性 pkg，因此 swagger 将不起作用。

要解决这个问题，首先在config目录下创建一个名为swagger.js的文件。

然后在swagger.js文件中添加如下内容

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