尝试将Rails 4应用程序部署到WebFaction，使用他们的文档并在本地获取错误

我试图通过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并在此处关注了webfaction的文档：

我采访了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，并且不会为Capistrano 3更新他们的文档一段时间。

我在他们的教程中完成了所有适当的步骤，在尝试运行“cap deploy：setup”或“cap deploy：check”等时出现了一堆错误。

pastebin中的错误， 这里 :(如下所示）

我已经尝试查看文件，但我不确定问题是什么，我不知道足够的ruby来排除故障。 我希望你能帮助我。

任何帮助都将是IMMENSELY赞赏和gittipp’ed !! 🙂

先感谢您！ 〜乔希

Answer 1

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。

我不太熟悉差异，但你得到的错误是cannot load such file -- capistrano/setup和这篇关于capistrano 3引用的文章require 'capistrano/setup'作为capistrano 3生成的Capfile中。

因此我猜测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您拥有的文件，但如果有，请尝试一下吗？

或尝试取出该行，看看是否有不同的错误？ 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？

Answer 2

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”

先尝试一下……

Answer 3

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
