我正在尝试通过Github将一个Rails 4应用程序部署到Webfaction，通过Capistrano 2.15.5。最初我安装了Capistrano 3并且遇到了错误，所以我最终安装了Capistrano 2.15.5并关注了webfaction的文档here：
我谈到了webfaction，他们建议我尝试使用旧的Cap 2版本，因为这是他们熟悉的内容，并且暂时不会为Capistrano 3更新他们的文档。
我在他们的教程中完成了所有相应的步骤，在尝试运行“cap deploy：setup”或“cap deploy：check”等时出现了一些错误。
pastebin中的错误here :(并在下面显示）

我猜你用Capistrano 3设置你的项目配置，我认为Capistrano 2的设置是不同的。
我对这些差异并不太熟悉，但您收到的错误是cannot load such file -- capistrano/setup和this post关于capistrano 3引用require 'capistrano/setup'的{{1}} capistrano 3产生的。
所以我猜测capistrano 2不存在该文件。我不知道capistrano 2是否有可以运行的生成器并让它们覆盖你拥有的文件，但是如果有，请尝试吗？ / p>
或尝试取出该行，看看是否有其他错误？或者还原你开始设置capistrano 3的提交并使用capistrano 2完全开始配置过程？

您是否在ruby v2.0下使用“gem install”安装了Capistrano 2？
rvm 2.0.0 宝石安装capistrano“你的版本”
先试试......

使用上限2.15.5部署rails 4应用程序时遇到了同样的错误。我做了研究，发现问题是语法，因为我从第3章切换到第2章。因此，如果您使用cap v2，则仅在capfile中加载命令工作，而Require命令仅在deploy.rb中使用。因此，如果您从3切换到2，请记住语法，因为cap v2和cap v3之间有很多变化。
注意：对于部署rails 4，应用程序2.15.5是您可以使用的稳定的capistrano版本。以下是适用于我的指南链接：https：//gist.github.com/brobertsaz/8660415
