Node.js的猫鼬模块未能在Heroku

开始前几天，我们的网站http://emaildelivery.herokuapp.com显示应用程序错误：Node.js的猫鼬模块未能在Heroku

"An error occurred in the application and your page could not be served. Please try again in a few moments.

If you are the application owner, check your logs for details."

我们Heroku的日志显示：

奇怪事情是，该网站在多个开发机器上本地正常工作。它只是在Heroku上死掉了。我们尝试升级/降级node.js版本和mongoose模块版本，但似乎无法解决此问题。

任何想法？

您是否尝试删除'node_modules'文件夹并执行'npm install'并查看结果？这就是Heroku正在做的事情。也许你已经将node_modules添加到存储库，并且正在上传并使其不一致。 – Mustafa

穆斯塔法处于我认为正确的轨道上。不知何故，你会在这里得到一个mongodb模块的混乱版本/ app/node_modules/mongoose/node_modules/mongodb。肯定npm和你的node_modules文件夹出了问题。 –

@Mustafa - 工作！请添加答案，我会将其授予您。 – Kane
