编译资产时“堆栈级别太深”

Question

在运行 brew upgrade 或其他更新我的 gems/ruby 版本后，我的 rake assets:precompile 任务不再工作。

我收到此错误：

rake aborted!

Tasks: TOP => assets:precompile

这是我的 Gemfile 的链接：http://www.pastie.org/3019470

其他 rake 任务，例如 db:migrate，继续按预期工作。这只会影响 assets:precompile 任务。

Answer 1

（重复我上面的评论，因为它似乎实际上是正确的答案。对于尚未使用它的任何人：rvm、rvm、rvm。学习它，爱它。）

引用三个不同版本的 ruby​​（1.9.1、1.9.2 和 1.9.3）的堆栈跟踪有一些非常奇怪的地方。我建议安装 rvm，创建一个干净的 gemset，然后再试一次。

Answer 2

这个问题可能是由于没有安装最新版本的 ruby​​gems 造成的。

如果您这样做：“gem update --system”，无论您是否使用 rvm，它都会起作用。
