Heroku Rails应用程序R11错误

Question

我在Heroku上使用Thin作为我的服务器部署Rails 3.2.11应用程序。当我推到Heroku时，它启动Thin很好，但是它似乎也尝试启动WEBrick。

我Procfile如下：

网站：束EXEC轨服务器-p $ PORT薄-e $ RACK_ENV

我的Heroku的日志：

为什么它是这样做的吗？我错过了什么？

Answer 1

事实证明，我使用的插件SyntaxHighlighter在其测试目录中有一些文件启动了WEBrick。我只是删除了这些，承诺，推动，它运作良好。

Answer 2

尝试使用Thin而不是WEBrick。您可以通过简单地增加给你的Gemfile中做到这一点：

gem 'thin' 

然后运行bundle install，提交新的Gemfile和Gemfile.lock的，然后推到Heroku的。

WEBrick不适用于生产用途。
