MongoDB 更新到 3.0 后 Heroku 应用程序崩溃

Question

MongoDB 今天强制将我的 Heroku 服务器从 2.6 更新到 3.0

现在我的应用程序在启动后不久就崩溃了，并出现错误：

我查看了他们的状态页面，发现 Mongo 已经将他们的服务器更新到 3.0 版本，而且更新现在应该是稳定的，因此我需要做一些事情。

在仔细研究之后。我发现我应该安装新的 "drivers" 以与版本 3.0 兼容。

我找到了这个linkhttp://docs.mongodb.org/manual/release-notes/3.0-scram/#upgrade-drivers

但它没有描述我可以如何在我的 Heroku 应用程序上更新驱动程序。

我正在使用他们的沙盒服务器。

我尝试联系他们的支持，但他们只是给了我同样的 link。

我也联系了 Heroku 支持。但他们只说：

You need to make sure that the libraries you are using for Mongo support the new version 3.0 of Mongo. It's not necessarily a 'driver' as such

这对我也没有帮助。

如果有帮助，这是我的 package.json 的内容。

  },
  "devDependencies": {},

  }
}

如果能帮助我了解如何更新我的 Heroku 应用程序上的驱动程序以与新的 3.0 MongoDB 兼容，我们将不胜感激。

Answer 1

您使用的是猫鼬 3.8.19。猫鼬的最新版本是 4.1.9。我将从这里开始：

$ npm install --save --save-exact mongoose@4.1.9

Answer 2

我遇到了完全相同的问题我做了以上所有事情，但没有任何效果。直到我从我的 package.json 中删除猫鼬并重新安装它才开始工作
