我正在尝试通过 github 将 Rails 4 应用程序通过 Capistrano 2.15.5 部署到 Webfaction。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 并在此处遵循 webfaction 的文档：

我与 webfaction 进行了交谈，他们建议我尝试旧的 Cap 2 版本，因为这是他们熟悉的版本，并且暂时不会更新 Capistrano 3 的文档。

我完成了他们教程中的所有适当步骤，并且在尝试运行“cap deploy：setup”或“cap deploy：check”等时遇到了一堆错误。

粘贴箱中的错误，此处：（如下所示）

我试过查看文件，但我不确定问题出在哪里，而且我不知道足够多的红宝石来解决问题。我希望你们能帮助我。

任何帮助将不胜感激和 gittipp'ed ！:)

先感谢您！〜乔希

我猜你是用 Capistrano 3 设置项目的配置，我认为 Capistrano 2 的设置是不同的。

我不太熟悉这些差异，但你得到的错误是cannot load such file -- capistrano/setup，这篇关于 capistrano 3 引用require 'capistrano/setup'的帖子是在Capfilecapistrano 3 生成的。

所以我猜测 capistrano 2 不存在该文件。我不知道 capistrano 2 是否具有可以运行并让它们覆盖您拥有的文件的生成器，但如果有，请尝试一下？

或者尝试取出那条线，看看你是否得到不同的错误？或者恢复您开始设置 capistrano 3 的提交并使用 capistrano 2 完全重新开始配置过程？

您是否在 ruby​​ v2.0 下使用“gem install”安装了 Capistrano 2？

rvm 2.0.0 gem install capistrano“你的版本”

先试试这个......

我在使用 cap 2.15.5 部署我的 rails 4 应用程序时遇到了同样的错误。我进行了研究，发现问题出在语法上，因为我从 cap 3 切换到 cap 2。因此，如果您使用 cap v2，则仅 load 命令在 capfile 中工作，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 capistrano 版本。这是对我有用的指南链接：https: //gist.github.com/brobertsaz/8660415
