我通过Magentify使用capistrano。我在archlinux上使用RVM作为常规用户。我使用Ruby 2.0.0并在我为此目的定义的gemset中运行gem install magentify。它安装了Capistrano 3.0.1和大约9个其他宝石。当我设置食谱时，我尝试了
cap -T
它写了
cap aborted!
undefined method `map' for :except:Symbol
/home/dirtymikeandtheboys/.rvm/gems/ruby-1.9.3-p484/gems/magentify-0.0.6/lib/nonrails.rb:24:in `block in <top (required)>'
我也尝试cap deploy得到了相同的结果（不确定我的预期。）如何开始尝试修复此问题？
编辑：使用命令--trace：
cap -T
cap aborted!

答案 0 :(得分：0)
修改的
这在Gem版本0.0.7中得到修复。我提交了一个补丁，它现在强制到Capistrano 2.X，这是唯一的兼容版本。最初的答案是错的，问题不在于Rake。
原始答案
似乎问题出在Rake而不是Capistrano上。您可能需要使用较旧版本的rake（可能是0.9.6），或更新Magentify gem以使用rake 10.也许您可以在该repo上打开一个问题。
修改
确认：它适用于rake 0.9.6。
您可以将此Gemfile添加到项目中：
source 'http://rubygems.org'
gem 'rake', '~> 0.9'
gem 'magentify'
然后像bundle exec cap -T
