适配器配置：
MongodbHerokuServer: {
adapter: 'sails-mongo',
url: process.env.MONGOLAB_URI
},
谁能帮帮我？我不知道该怎么做才能解决这个问题。
【问题讨论】：
-
MongoDB 在 heroku 上不是免费的，你要付费吗？如果是，您可能需要为连接设置凭据信息
-
如果你在适配器配置中看到，我放了一个 MONGOLAB 的 Env 变量。 heroku 允许您创建一个免费的实例 mongolab。 @jaumard
-
确保 MONGOLAB_URI 正确，尝试通过控制台连接
-
是
MongodbHerokuServer定义的唯一适配器吗？ -
不，但是当我尝试删除生成默认 Sails 的其他适配器时，我的应用程序运行了。谢谢！！！ @Meeker
