MongoDB刚刚强制将我的Heroku服务器上的更新从2.6更新为3.0

现在，我的应用在启动后不久因以下错误而崩溃：

我检查了他们的状态页，发现Mongo已将其服务器更新为3.0版，而且该更新现在应该稳定了，因此这是我需要做的事情。

在看了一些之后。我发现应该安装新的“驱动程序”以与3.0版兼容。

我发现此链接http://docs.mongodb.org/manual/release-notes/3.0-scram/#upgrade-
drivers

但这并没有描述我如何才能在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人员，但他们只是给了我相同的链接。

我也联系了Heroku支持。但是他们只说：

您需要确保用于Mongo的库支持新版本的Mongo 3.0。不一定是这样的“司机”

这也无济于事。

如果有帮助，这是我的package.json的内容。
