运行 `bundle install` 时部署 capistrano 因 ssh 错误而失败

Question

我正在使用Capistrano 3 将 Rails 项目部署到 VPS 服务器（CentOS 6.5）。

上次大约 2 个月前我可以毫无问题地部署，但现在在 VPS 服务器上运行 bundle install 时，我无法通过 ssh 错误进行部署。

我将 ruby​​ 版本 2.0.0-p451 更新为 2.1.1，但它不会更改错误消息。

这是错误信息：

我可以像这样在服务器上通过# gem install rake 手动安装rake (10.3.2)：

rake's executable "rake" conflicts with /usr/local/rbenv/versions/2.1.1/bin/rake
Overwrite the executable? [yN]  y
Successfully installed rake-10.3.2

但即使更新后部署错误仍然存​​在。

我应该怎么做才能消除错误？ 任何建议表示赞赏。

Answer 1

看起来服务器“au-m.rubygems.org”已关闭。

这就是错误的原因。
