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

Question

当尝试运行我的简单 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 缓存清除不起作用。 我已经尝试重新安装 grunt-cli 和 sails-swagger 了...... 这里有人有解决办法吗？

问题 github.com也打开了...

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 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找不到属性 pkg，因此 swagger 将无法工作。

要解决此问题，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'
  }
};
