Rails4：如何提供gem特定的javascript文件？

Question

我将一个工作的rails应用程序复制到另一个目录中，并使用重命名Gem重命名它。

大多数rails功能都正常，但我无法提供与gems捆绑的资产，特别是来自bootstrap-slider-rails的js文件

我比较了我的application.rb，Gemfile和application.js，它们在两个应用程序中是相同的。

我已尝试重新卸载并安装宝石

应用程序之间的简单比较并不能解决问题。

以下是我在两个应用中验证的文件相同：

1. 的Gemfile
2. application.rb中
3. application.html.haml
4. 的application.js

有关我应该如何调试的建议吗？

谢谢！

#  # If you want your assets lazily compiled in production, use this line

Bundler.require(:default, Rails.env)

尝试删除gemfile.lock并再次运行bundle install。

另请参阅this关于复制和部署rails应用的帖子。如果没有，则应删除.git文件并运行git init。

我不是百分百肯定这会解决你的问题，但我怀疑你有宝石问题。
