を介してデプロイしようとしてcapistrano
いますが、何らかの理由で次のようになっています。
/Users/mysite/.rvm/gems/ruby-1.9.2-p318@fbadapter/gems/json-1.4.6/lib/json/common.rb:146:in `initialize': can't convert Hash into String (TypeError)
from /Users/mysite/.rvm/gems/ruby-1.9.2-p318@fbadapter/gems/json-1.4.6/lib/json/common.rb:146:in `new'

from ./config/deploy.rb:35:in `block in load'
私の問題の行は次のconfig/deploy.rb
とおりです。
after 'multistage:ensure' do
role_from_chef :db, 'app', :limit => 1, :primary => true # perform db operations on one of the app servers
role_from_chef :web, 'app'
role_from_chef :app
role_from_chef :queue
role_from_chef :cron
end
2行目は35行目です
更新されたコード
def role_from_chef(cap_role, *roles)
