Javascript不能在Ruby on Rails部署模式下工作

当我的Ruby on Rails项目处于部署模式时，我无法获得任何javascript运行。我有一个js在vendor/assets/javascript/theme/index-slider.js。它在这个文件中有一个警告来测试javascript是否正常工作:

alert('TestTestTest');

当我在开发模式下运行项目时，所有javascript都正常运行。此外，如果我将<script>alert("Testme");</script>添加到我的index.html.erb文件中，该javascript将在生产模式下运行。

我一直在运行rake assets:precompile和RAILS_ENV=production rake assets:precompile时进行更改以及重新启动服务器

如何让Javascript在生产模式下运行?(另外，我对Ruby on Rails相当陌生，所以我不确定我应该包括哪些文件/信息来帮助。)谢谢。
