不知何故，这是相关的，但我不确定如何/为什么？
刚刚通过 RVM 的命令从 Ruby 1.9.2-p180 升级到 1.9.2-p290 rvm upgrade……现在我的资产管道已经“损坏”了。
在此期间rvm upgrade ...，我注意到每个 gemset 存在以下错误：
ERROR: Error running 'rvm gemset pristine' under ,
please read /Users/meltemi/.rvm/log//gemset.pristine.log
我让升级继续，因为 gemset.pristine.log 中没有太多有趣的东西......此外，/Users/meltemi/.rvm/log//gemset.pristine.log不（不能？）存在于那个确切的路径中吗？路径名中有两个连续的“//”？反正...
测试一个小型应用程序，尽管它启动并似乎运行它并没有加载任何资产（图像、css 等）。开发日志有很多Not Found关于这些缺失资产的错误（见下文），即使它们存在于app/assets/imagesandapp/assets/stylesheets等...？
有人知道这里发生了什么吗？似乎管道已经以某种方式崩溃了......好像 Rails 不再知道在应用程序/资产中寻找资产，也许？我如何测试/验证/修复/重新激活这个“管道”？
