在这里我们知道迁移文件存在，但是当我给 rake db:migrate 时它显示空白而不是创建
FrescoMac002:Roorah frescoadmin$ rake db:migrate
/Users/frescoadmin/.rvm/gems/ruby-2.1.2@global/gems/bundler-1.6.2/lib/bundler/runtime.rb:222: warning: Insecure world writable dir /usr/local in PATH, mode 040777
Starting up a new ElasticSearch client with
FrescoMac002:Roorah frescoadmin$
在我的数据库中没有创建任何东西，即使我尝试了单个迁移文件也是这样
rake db:migrate:up VERSION="20140822150851"
请帮帮我
