我一直在尝试使用 Capistrano 部署 Rails 应用程序，但是当我运行时，cap production deploy我得到：
(Backtrace restricted to imported tasks)
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing as

Net::SSH::AuthenticationFailed: Authentication failed for user

(See full trace by running task with --trace)
我试过跑步cap production rvm:check --trace，我得到了这个

Tasks: TOP => rvm:check
这就是我的 ssh 部分的deploy.rb样子：
set :keep_releases, 5
set :rvm_type, :user
set :rvm_ruby_version, 'ruby-2.3.1'
set :ssh_options, { forward_agent: true }
# set :ssh_options, { forward_agent: true, user: fetch(:user), keys: %w(~/.ssh/mykey.pem) }
我有这条线config/deploy/production.rb
server "12.34.56.789", user: "deploy", roles: %w{app db web}, my_property: :my_value
当我运行evalssh-agent`` 并且ssh-add ~/.ssh/id_rsa它工作正常。
我在这里错过了什么吗？我该如何解决这个问题？
谢谢你。
