Ruby on rails 未定义变量：“$navbar height”。RubyonRails中的错误

我刚刚部署了该站点，出现以下错误：

Sass::SyntaxError in MainSite#home

Undefined variable: "$navbar-height".

我没有定制任何东西，相同的代码可以在本地服务器上工作，但不能在生产服务器上工作。我在过去5天里一直在研究，读了10多篇文章，但都没有效果。请提供您的建议，以下是日志跟踪：

你在使用引导程序吗？如果是，那是哪一个？

---

如果您使用的是引导gem，那么请忽略所有引导gem并使用资产中的文件。

一般要点：如果它在环境设置为开发时工作，但在设置为生产时不工作，那么这是由于项目配置不同而导致的错误。在rails中，生产配置包括一系列优化，例如如何构建资产，或者不在生产中构建资产

除此之外，我将首先看看它们的部署有什么不同。它们都使用相同的gems吗？您可以比较Gemfile.lock，并检查本地计算机上没有未签入git/svn的内容

另外，看看您的系统环境是否相似，您可以了解为什么人们喜欢容器/码头工人。例如，您在mac上开发，但在生产环境中运行在windows主机上

更新：以上是一般建议，以下是基于错误的建议

---

查看rails_admin gem，您可能希望查看引导问题的疑难解答。如果这些解决方案都无法解决您的问题，请告知我。分析跟踪记录后，我将按照以下步骤进行操作： 将本地Gemfile和Gemfile.lock复制到生产服务器并运行以下命令：

$ rvm use 2.1.3
$ rvm gemset empty
$ bundle install

---

您需要预编译资产，检查development.rb文件并包括所有sass文件

config.assets.precompile+=%w rails\u admin/base/theming.scss

---

将这一行添加到development.rb文件中

我已经从我的应用程序代码中删除了这一行下面的代码

config.assets.precompile += %w( *.js *.css)

---

请在MainSitehome中发布错误所在的代码，也请在/theming.scs中发布代码查看下面的疑难解答链接，让我知道这是否适用于您我已尝试过开发模式，但仍然出现错误我重置gem并复制gemlock文件，它工作完美我已经决定使用宝石重置，但可能是你的想法工作：谢谢
