有人能帮我吗？我不知道该怎么解决这个问题

根据您的评论，您的问题是sails有时会混淆多个名称适配器。下面还概述了您的问题和解决方案

---

MongoDB在heroku上不是免费的，您要付费的吗？如果是，您可能需要为Connexion设置凭据信息如果您在适配器配置中看到，我将一个Env变量设置为mongonab。heroku允许您创建一个自由实例@jaumardmake确保Mongodab_URI正确，尝试通过您的控制台连接MongodbHerokuServer唯一定义的适配器？没有，但当我尝试删除生成默认SAIL的其他适配器时，我的应用程序运行了。谢谢你@Meeker感谢链接Meeker，此解决方案对我有效：

MongodbHerokuServer: {
    adapter: 'sails-mongo',
    url: process.env.MONGOLAB_URI
  },
