Rails 3.2 rake编译问题

Question

突然不能推到Heroku!错误消息说:

未初始化的常数Haml :: Util :: Sass

(相同的代码和库在2天前工作正常!)

编译显然在这行application.rb上失败了:

Bundler.require(*Rails.groups(:assets => %w(development test)))

在尝试编译时,我得到了这个:

无法检测rake任务确保您可以在$ bundle exec rake -P没有环境变量且使用Gemfile的生产组的情况下针对您的应用运行.这可能是故意的,如果您希望运行rake任务取消构建(CTRL + C)并修复错误然后提交修复:rake aborted!
未初始化的常数Haml :: Util :: Sass

Answer 1

你正在使用haml 3.1.6,这是在这个版本的sass上打破.

最好的解决方法是更新到最新版本的haml 4.0.x:

$ bundle update haml haml-rails
