【问题描述】：

我正在尝试在本地预编译我的应用资产。当我跑步时

bundle exec rake assets:precompile --trace

我得到一个堆栈级别太深的错误：

** Execute assets:precompile

Tasks: TOP => assets:precompile

自从assets:precompile 工作后发生了什么变化：我从 ruby 1.9.2 迁移到 1.9.3。不明白为什么它说它在样式表上失败了。有什么想法可能是错的吗？

【问题讨论】：

嗯，你试过bundle update rake吗？我什至可能会推荐bundle update，除非你有特定的版本依赖。
@CyleHunter：10.0.3 是最新的。此外，这意味着 Rails 较新，因为它们总是依赖于特定版本的 rake。
@KoriJohnRoys：p194 已经过时了几个补丁级别。 1.9.3p327 会发生什么？
假设我应该补充一点，我在 Rails 3.1.1 上。是的，我已经运行了bundle update。
@KoriJohnRoys：3.1.1 真的很旧，这可能是问题所在。在 1.9.2 上尝试更新到最新的 3.1.x，检查它，然后再次尝试移动到 1.9.3。很有帮助的机会。

【解决方案1】：

终于为 Google 找到了正确的方法：“scss 堆栈级别太深”。事实证明这是一个 sass 问题："rake aborted! stack level too deep" while deploying to Heroku

TL;DR:

我的 Gemfile 中有这个：

gem 'sass-rails', '~> 3.1.4'

需要这个：

gem 'sass-rails', '3.1.4'
