【问题描述】：
所以...我有一个使用引导导航栏的 Rails 应用程序。这一切都在我的机器上本地工作，但在推送到 Heroku 后，它使一切都接受导航栏。 Take a look at the heroku site。这里是link to the github repo，如果您需要引用它。
我尝试过的事情
我运行rake assets:precompile 没有运气。我已将config/environments/production.rb 添加到config.assets.compile = true，我读到这对性能不利，但无论如何都尝试了它只是为了看看它是否会起作用（它没有）。
如果答案在另一篇文章中，我深表歉意……我只是觉得我已经浏览了其中的大部分内容并尝试了我能找到的所有内容。我显然错过了一些东西。提前感谢您的帮助。

【问题讨论】：
-
部署后......你的heroku日志是什么样的......通常会发生这种情况，因为你的css中某处有错误。您通常可以从 heroku 日志中提取该错误。
-
菜单在那里，但没有应用样式。您是否尝试过手动导入 Bootstrap（不是通过您的 CSS 文件）？
-
当我在你的
<head>中链接到/assets/base/bootstrap.css之前 CSS 被链接时，菜单工作（如预期）。 -
Like this@Roy?如果是这样...我部署了该更改并执行相同的操作。
-
我在@toddmetheny 上面添加了日志。
