目前我收到一个h10应用程序崩溃错误，即使它在本地工作，日志似乎没有帮助。该日志首先出现错误

错误R10（启动超时） - ＆gt; Web进程无法绑定到$ PORT 在错误代码= H10处获得错误之前60秒启动 desc =＆＃34; App崩溃＆＃34; method = GET path =＆＃34; /favicon.ico" 主机= maitri-compassionate-care-app.herokuapp.com request_id = 602ed7f2-118f-43b2-b57f-077b89c7b2c4 fwd =＆＃34; 98.248.251.49＆＃34; dyno = connect = service = status = 503 bytes =

这是日志：

我已经尝试过heroku restart，heroku ps restart，以及rake rails update bin但是它们似乎都没有帮助。除了超时和崩溃之外，我不确定如何获得更具体的错误。

Answer 1

您的应用看起来像是使用WEBrick作为网络服务器。这适用于本地开发环境，但不应在生产环境中使用，例如部署到Heroku时。

Heroku建议使用puma作为生产服务器。详细说明可以在他们的开发中心文档中找到。

Answer 2

来自Heroku docs：

在Common Runtime中，web dyno必须在启动后60秒内绑定到其指定的$PORT。如果没有，则由dyno管理器终止，并记录R10 Boot Timeout错误。进程可以在绑定到$PORT之前和之后绑定到其他端口。

根据您的日志，WEBrick在端口3000而不是$PORT上运行，使$PORT未绑定以延迟60秒超时。必须将WEBrick配置为在Heroku分配的端口$PORT上启动。你可以使用Procfile。

创建一个名为Procfile的{{1}}，其名称如下：

web: bundle exec rails server -p $PORT

然后（来自文档）：

要让Heroku使用您的Procfile，请将Procfile添加到应用程序的根目录，然后推送到Heroku：
$ git add .
$ git commit -m "Procfile"
$ git push heroku

在本地工作时获取Heroku h10错误
