Capistrano未能部署我的Ruby on Rails应用程序。自从我之前成功部署以来，我没有更改任何配置文件（Capfile，deploy.rb等）。

本地红宝石版本：

chris-iMac:untrackedlatest Chris$ ruby -v
ruby 2.1.5p273 (2014-11-13 revision 48405) [x86_64-darwin14.0]

远程ruby版本：

untracked@untrackedprod:/srv/untracked/current$ ruby -v
ruby 2.1.5p273 (2014-11-13 revision 48405) [x86_64-linux]

自上次成功部署以来，我没有对ClientAliveInterval / ServerAliveInterval进行任何改动。

我能够成功SSH到服务器。

Capistrano宝石：

Using capistrano 3.4.0
Using capistrano-bundler 1.1.4

服务器正在运行Ubuntu 14.04

非常感谢任何帮助！

我遇到了同样的问题。我通过两个步骤解决了这个问题：

  1. 我只需在服务器文件~/.ssh/authorized_keys中添加一行，内容就是我的本地文件~/.ssh/id_rsa.pub。
  2. 由于我的mac和VirtualBox VM上有两个相同的帐户名，而我在服务器文件~/.ssh/authorized_keys中取消注释其中一个，所以一切顺利。

    3. 祝你好运！

它可能不是正确的解决方案，但对于我从新标签/终端开始部署工作。我认为需要重新启动shell。
