【问题描述】：

我正在尝试使用 capistrano 3.2.1 通过 ssh 设置从 Windows 机器到远程主机的部署。但在第一次运行时，我收到以下错误：

cap production deploy --trace --verbose

SSHKit::Runner::ExecuteError: Exception while executing on host #&lt;Capistrano::Configuration::Server:0x29b1460&gt;: undefined method `colorize' for :location:Symbol

我的版本是这样设置的：

deploy.rb

lock '3.2.1'

set :application, 'myapp.com'
set :user, "deploy"
set :repo_url, 'git@bitbucket.org:me/myapp.com.git'
set :use_sudo, false
set :deploy_to, '/var/www/#{application}'
set :ssh_options, { :forward_agent => true }
set :deploy_via, :remote_cache
set :pty, true

Capfile

require 'capistrano/setup'
require 'capistrano/deploy'

Production.rb

set :location, "myapp.com"
role :app, :location
role :web, :location
role :db,  :location, :primary => true

server 'myapp.com', :roles => [:app, :web, :db], :primary => true

已安装的 gem 和版本：

*** LOCAL GEMS ***

bigdecimal (1.1.0)
capistrano (3.2.1)
chunky_png (1.2.9)
colorize (0.7.3)
compass (0.12.2)
foundation (1.0.4)
fssm (0.2.10)
i18n (0.6.11)
io-console (0.3)
json (1.5.5)
minitest (2.5.1)

rdoc (3.9.5)
rubygems-update (2.1.11)
sass (3.2.12)
sshkit (1.5.1)
thor (0.18.1)

有谁知道该怎么做或如何调试它？我在谷歌搜索中找不到任何东西......我看到一些关于 colorize gem 必须是 0.6+，但如上所示，我有最新的（0.7.3 atm）。

【解决方案1】：

好的，发现：这似乎与 Ruby gems 中的版本兼容性有关。发现，它可以在我的另一台笔记本电脑上运行，然后比较配置 - 工作机器正在运行

sshkit (1.3.0)

我将 sshkit 从 v.1.5.1 降级为 1.3.0，解决了它。
