Heroku deployment error H10 (App crashed)
提问by bskool

I ran into the same error above, app was crashing on heroku (running fine in dev) but error logs on heroku were not revealing any clues. I read other answers on this page and broke out in a sweat after seeing "rebuilding the app." I figured maybe I could get in the heroku console and look around. I did and even the console crashed, but this time it told me why. It was some obscure variable I forgot to delete during a troubleshooting session hours earlier. I am not saying you will run into the same problem, but I found more info when I tried to go through the console. Hope this helps.
我遇到了上面同样的错误，应用程序在 heroku 上崩溃（在 dev 中运行良好）但 heroku 上的错误日志没有透露任何线索。我在此页面上阅读了其他答案，并在看到“重建应用程序”后大汗淋漓。我想也许我可以进入 heroku 控制台并环顾四周。我做到了，甚至控制台也崩溃了，但这一次它告诉了我原因。这是我在几个小时前的故障排除会话中忘记删除的一些晦涩的变量。我并不是说你会遇到同样的问题，但是当我尝试通过控制台时我发现了更多信息。希望这可以帮助。
$ heroku run rails console

I was having the same issue. Logs weren't giving me any clues either. So I scaled down and scaled back up the dynos. This solved the problem for me:
我遇到了同样的问题。日志也没有给我任何线索。所以我缩小并缩小了dynos。这为我解决了问题：
heroku ps:scale web=0
Waited a few seconds...
等了几秒...
heroku ps:scale web=1

$heroku run rails console
This is the best option since it will give you an error in your terminal which will be much more detailed than the 'app crashed' error in your Heroku logs.
这是最好的选择，因为它会在你的终端中给你一个错误，这比你的 Heroku 日志中的“应用程序崩溃”错误要详细得多。

$ heroku restart
helped me get my dyno running again. I'm new to Heroku but glad I know now.
帮助我让我的 dyno 再次运行。我是 Heroku 的新手，但很高兴我现在知道了。

this happened to me when I was listening on the wrong port
当我在错误的端口上收听时，这发生在我身上
I changed my listen() to "process.env.PORT" so:
我将我的 listen() 更改为“process.env.PORT”，因此：
http.listen((process.env.PORT || 5000), function(){
console.log('listening on *:5000');
});
instead of
代替
http.listen(5000, function(){
console.log('listening on *:5000');
});

Had same problem this evening. Not a very helpful error so I tried running in the console
今天晚上有同样的问题。不是一个很有帮助的错误，所以我尝试在控制台中运行
heroku run rails c
it failed and gave me a much more helpful error. I had neglected to delete a method call in production. Once I fixed that, the app worked fine.
它失败了，给了我一个更有帮助的错误。我忽略了删除生产中的方法调用。一旦我解决了这个问题，该应用程序运行良好。

I solved this problem by pushing to Git:
我通过推送到 Git 解决了这个问题：
git add .
git commit -am "some text"
git push
then push to Heroku:
然后推送到 Heroku：
git push heroku
then rake db:migrate on Heroku:
然后在 Heroku 上 rake db:migrate ：
heroku run rake db:migrate

I managed to not include my .gitignore file -> that breaks heroku. #doh
我设法不包含我的 .gitignore 文件 -> 破坏了 heroku。#doh
Here is a working .gitignore file
这是一个有效的 .gitignore 文件

To create a .gitignore file, in terminal navigate to your apps directory and use the following command
要创建 .gitignore 文件，请在终端导航到您的应用程序目录并使用以下命令
touch .gitignore
Then you can open it up in a your text editor and put the above code into it.
然后你可以在你的文本编辑器中打开它并将上面的代码放入其中。

In my case i was using ENV variables in my app, but it was not set in heroku config.
在我的例子中，我在我的应用程序中使用了 ENV 变量，但它没有在 heroku 配置中设置。
heroku console gave proper error:
heroku 控制台给出了正确的错误：
heroku console
`validate_options': Missing required arguments: aws_access_key_id, aws_secret_access_key (ArgumentError)
Then set the ENV config
然后设置ENV配置
heroku config:set AWS_ACCESS_KEY_ID='key'
Restart the Heroku
重启 Heroku
heroku restart
it works!!
有用！！

I was getting this same H10 app crashed error in Heroku. I clicked 'restart all dynos' in the heroku interface, and problem solved.
我在 Heroku 中遇到了同样的 H10 应用程序崩溃错误。我在 heroku 界面中单击了“重新启动所有 dynos”，问题解决了。
