我正在 Heroku 上部署 Rails 3.2.11 应用程序，并使用 Thin 作为我的服务器。当我推送到 Heroku 时，它启动 Thin 就好了，但它似乎也尝试启动 WEBrick。

我的Procfile如下：

网络：捆绑 exec rails server -p $PORT thin -e $RACK_ENV

为什么要这样做？我错过了什么？

事实证明，我使用的一个插件 SyntaxHighlighter 在它的测试目录中有一些文件可以启动 WEBrick。我刚刚删除了那些，提交，推送，并且效果很好。

尝试使用 Thin 而不是 WEBrick。您可以通过简单地将其添加到您的 gemfile 来做到这一点：

gem 'thin'

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

WEBrick 不适合生产使用。
