我一直在尝试将heroku与我的rails应用程序一起使用。我有宝石安装heroku并将其列在我的gemfile中，但每次我尝试用它做任何事情我都会收到这个错误......

我是铁杆新手所以如果有人知道什么是错的话，我会很感激。我用谷歌搜索了它，但似乎无法找到同样的问题。
这些是我目前安装的宝石列表，可能是原因：

所有其他宝石都可以正常工作。只有Heroku才会引发错误。
感谢。

我认为我已经完成了宝石更新+捆绑更新，这就是搞乱它的原因。
我已经卸载了mime-types 1.17.1，现在看起来一切正常。我不得不卸载它。即使我将应用程序设置为使用版本1.16，当我尝试使用Heroku做任何事情时，它仍然会出现相同的错误。

您不需要将Heroku包含在您的gemfile中。

此问题已通过mime-types 1.17.2修复，刚刚发布。我无法在Mac OS X上重现这个问题，但问题很容易解决。
