Capistrano 部署：更新失败，但设置和检查工作

Question

我是新手，如果这是一个愚蠢的问题，我深表歉意，但谁能帮我破译这个部署错误？我终于设法让 'cap deploy:setup' 和 'cap deploy:check' 正常运行。现在，我被困在“上限部署：更新”。从错误输出来看，我的部署文件似乎有问题，但我不知道问题可能是什么。 shell 输出和部署文件如下。任何帮助将不胜感激！

一些背景：我正在部署到正在运行乘客的朋友的服务器。我们正在使用 ruby​​ 1.9.2-p290、rails 3.1.3、capistrano 2.11.2 和 MacOS 10.6。

这是部署错误输出的示例：

my-MacBook-Pro:projectfolder myuser$ cap deploy:update
  * executing `deploy:update'
 ** transaction: start
  * executing `deploy:update_code'
    updating the cached checkout on all servers

... etc.

错误输出的其余部分也指向 capistrano 文件夹。输出似乎太长，无法完整包含在内。但如果有帮助，我可以提供其余的！

这是部署文件：

$:.unshift(File.expand_path('./lib', ENV['rvm_path'])) # Add RVM's lib directory to the load path.
require "rvm/capistrano"                  # Load RVM's capistrano plugin.

set :application, "Project"

set :scm, "git"
set :repository,  "ssh://git@server.example.ca/usr/local/git_root/project.git"
set :user, "deploy"

#set :rvm_bin_path, "/usr/local/rvm/bin"
set :rvm_ruby_string, "ruby-1.9.2-p290@project"
set :normalize_asset_timestamps, false

ssh_options[:forward_agent] = false

set :branch, "master"

set :deploy_via, :remote_cache

set :deploy_to, "/usr/local/www/sites/project.example.ca/"

set :use_sudo, false

set :domain, 'project.example.ca'

role :app, domain

Answer 1

错误是行

No such file or directory - git ls-remote ssh://git@server.example.ca/usr/local/git_root/project.git master (Errno::ENOENT)

所以它在检出存储库时失败。为什么你有 ssh 前缀？指定用户 (git@) 时，您也不应该有协议 - 存储库应该设置为

git@server.example.ca/usr/local/git_root/project.git

或者项目的 git 存储库的任何实际 URL。

仅供参考 - deploy:setup 和 deploy:check 都没有真正检查代码，这就是这两个工作的原因。
