【问题描述】：

我正在尝试关注this guide 在 ubuntu (12.10) 上设置一个带有 nginx、unicorn 和 capistrano 的 rails 堆栈。我决定使用 RVM 进行 ruby​​ 安装。

到目前为止我安装了什么：

所有依赖库（imagemagick、git、mysql-server 等） nginx (1.2.1) rvm (1.17) 和 ruby​​ (1.9.2) 宝石：rails (3.1.6)、unicorn (4.4.0)、capistrano (2.13.5)、...

在本地，我进入

$ capify .

有效（在顶部提到的部署指南中，在第 8 页）

但我被困在下一部分“cap deploy:setup”（在指南上，第 12 页）：

$ cap deploy:setup

而且它似乎并不依赖于 deploy:setup。

我随机尝试了一些其他 capistrano 命令，但总是收到相同的错误消息“您必须准确指定值或块之一 (ArgumentError)”

有什么想法吗？

【参考方案1】：

固定。

这是一个愚蠢的错误，我在 deploy.rb 中有两次 'set :scm, :git'。
