Rails 4 + Capistrano 3：部署：检查不工作

我可以成功SSH到我的服务器。 但是，当我进行deploy:check ，它给了我：

with --trace) The deploy has failed with an error: # Nets-Mac-Pro:mysite emai$ 

无论我输入什么，它都不起作用，而且一切都在公开场合。 我该如何解决？

这是我的deploy / staging.rb：

 set :rails_env, 'staging' set :stage, :staging role :app, %w{mysite-staging.nettheory.com} role :web, %w{mysite-staging.nettheory.com} role :db, %w{mysite-staging.nettheory.com} server 'mysite-staging.nettheory.com', user: 'nt_deployer', roles: %w{web app db}, primary: true set :use_sudo, false set :deploy_via, :copy 

当我没有设置ssh_options时会发生上述情况。 这是我设置时发生的事情：

 set :ssh_options, { user: 'nt_deployer', # overrides user setting above keys: %w('/Users/emai/Downloads/ilook_ec2_07182014.pem'), forward_agent: true, auth_methods: %w(publickey) # password: 'please use keys' } Nets-Mac-Pro:mysite emai$ be cap staging deploy:check INFO[de1d1563] Running /usr/bin/env mkdir -p /tmp/mysite-staging/ on mysite-staging.nettheory.com DEBUG[de1d1563] Command: /usr/bin/env mkdir -p /tmp/mysite-staging/ cap aborted!
