部署 一直碰到 File to import not found or unreadable: bootstrap-responsive. 的问题
在部署到 Ubuntu 的过程中，遇到一个奇怪的问题，搜索了半天，网上的解决方案都不行，只能来求助了。 问题现象： 在 windows 开发的，windows 上一切正常； 在页面上一直显示：We're sorry, but something went wrong.
日志显示：

求解决方案？谢谢
自己更新一下进展， 找到一篇最新的文章，描述这个问题： http://stackoverflow.com/questions/19948584/bootstrap-not-work-in-rails-application 大意是 bootstrap 的版本有问题；我看了一下老版本的配置文件
- bootstrap-sass (2.1.1.0) --windows 老版本
- bootstrap-sass (3.0.3.0) --Ubuntu 的是这样的；
Bootstrap-responsive has been removed since Bootstrap 3.0.
3.0 is mobile first design, and responsiveness is native now.
Remove that require statement, no need now.
Update
Dexter(OP) finally solved the problem by going back to 2.3. Though the case is rare, I think two lessons can be learned:
Always add version to critical gems.
Always use bundle install or bundle(default to install). Only use bundle update when it's really necessary and you are fully prepared.
如 stackoverflow 哥们说的，关键是要精确制定版本好： Always add version to critical gems. Always use bundle install or bundle(default to install). Only use bundle update when it's really necessary and you are fully prepared.
@Martin91 ，恢复一批已经升级的 gem，有快捷的方法吗？
