Question

我按照this教程使用 capistrano 部署 Rails 4 应用 AWS 并且很难解决这个问题。

当我运行cap production deploy时，它失败并出现以下错误

Net::SSH::AuthenticationFailed: deploy

根据此SO帖子，我尝试在net-ssh和2.7.0 net-ssh-gateway处锁定1.2.0，但错误仍然存在。任何帮助表示赞赏。

环境：

OS - Ubuntu 14.04 LTS

Ruby - 2.2.3p173

Rails - 4.2.5

Capistrano - 3.4.0

net-ssh - 2.7.0

net-ssh-gateway - 1.2.0

问题出在net-ssh上，正如Sparkmasterflex正确回答的那样，但是这会让capistrano工作正常，它可能会破坏你的应用程序：
这些步骤为我修复了capistrano和rails：

在你的Gemfile中添加gem'net-ssh'，'2.7.0'
运行捆绑包更新net-ssh
运行捆绑包（只是为了确保一切正常“
运行gem uninstall net-ssh -v 2.8.0

如果您是rails用户，您现在应该可以同时运行rails服务器和capistrano。

Rails 4 + Capistrano + AWS Net :: SSH :: AuthenticationFailed：deploy
