Rails 4，Capistrano 3.0.0无法加载此类文件-部署

我刚刚运行了捆绑包更新，并且capistrano已更新为3.0.0，但是现在当我运行cap deploy时出现错误，无法解决该问题。直到进行此更新，我每天都在更新服务器，没有问题。

I just ran bundle update and capistrano got updated to 3.0.0 but now when I run cap deploy I get an error and can't figure out how to fix this. I have been updating my server every day without problem until this update.

cap aborted!
cannot load such file -- deploy
/home/mark/rails_apps/myapp/Capfile:1:in `load'
/home/mark/rails_apps/myapp/Capfile:1:in `<top (required)>'

capfile

load 'deploy'
load 'deploy/assets'
load 'config/deploy' # remove this line to skip loading any of the default tasks
