编译资产时“堆栈级别太深”
在运行brew upgrade或其他更新我的gems / ruby版本之后，我的rake assets:precompile任务不再有效。
我收到此错误：

这是我的Gemfile的链接： http ： //www.pastie.org/3019470
其他rake任务（如db：migrate）继续按预期工作。 这仅影响资产：预编译任务。
（重复我的评论，因为它似乎确实是正确的答案。对于任何尚未使用它的人：rvm，rvm，rvm。学习它，喜欢它。）
堆栈跟踪有一些非常奇怪的东西，引用了三个不同版本的ruby（1.9.1,1.9.2和1.9.3）。 我建议安装rvm ，创建一个干净的gemset，并再次尝试。
此问题可能是由于未安装最新版本的rubygems引起的。
如果你这样做：“gem update –system”，无论你使用rvm还是不使用rvm都会有效。
