问题描述

我正在尝试在Heroku上部署MEAN堆栈(MongoDB-Express-Angularjs-Nodejs)应用程序.用git push heroku推送代码后，出现以下错误缩放dynos ...失败！找不到该格式".

I am trying to deploy a MEAN stack (MongoDB-Express-Angularjs-Nodejs) app on Heroku. After I push my code with git push heroku I get the following error "Scaling dynos... failed! Couldn't find that formation".

我检查了没有运气的解决方案.我创建了一个Procfile，但这没有帮助.我仍然遇到相同的错误.

I have checked for a solution with no luck. I created a Procfile, but that didn't help. I still get the same error.

关于如何启动和运行它的任何想法.我将包含更多代码，但我不知道问题出在哪里，所以请提出，我将包含必要的代码.

Any ideas on how I could get this up and running. I would include more code but I don't know where the problem is so please ask and I will include that code that is necessary.

推荐答案

好的，所以我发现了我的问题所在.当我看到错误日志时，很明显我遇到了MongoDB连接错误.我必须指出正确的MongoDB实例，它的工作原理很吸引人.下面发布的是我修改"server.js"文件后用来纠正该问题的特定命令.

Okay so I found what was my problem. When I saw the error logs it was painfully obvious that I was having a MongoDB connection error. I had to point to the correct MongoDB instance and that worked like a charm. Posted below are the specific commands I used to correct the issue after I modified the "server.js" file.

最终使我能够在Heroku上部署的东西！

What finally worked to allow me to deploy on Heroku!

>     $ heroku open
>     $ git push heroku master
>     $ git commit -m "myMessage"
>     $ git add <file>
>     $ git status

提交消息:我更新了mongoDB连接，然后提交，并将更改推送到Heroku，现在该应用程序已在线加载.
