我正在尝试将 Node.js 应用程序部署到在 DigitalOcean 上运行的 VPS 上，到目前为止，我已经康复了……非常远。我对 *nix 的理解非常有限，所以请多多包涵:)
我可以使用我的 SSH 密钥以 root 身份 ssh 进入我的 VPS（Ubuntu 13.04 x32），没有任何问题。当我在本地机器上运行“$cap deploy:setup”时，我得到了这个结果：
* 2013-09-11 12:39:08 executing `deploy:setup'
* executing "mkdir -p /var/www/yable /var/www/yable/releases /var/www/yable/shared /var/www/yable/shared/system /var/www/yable/shared/log /var/www/yable/shared/pids"
servers: ["162.243.1.207"]

当我运行“$cap deploy:check”时，我得到以下输出：

The following dependencies failed. Please check them and try again:
--> `/var/www/yable/releases' does not exist. Please run `cap deploy:setup'. (162.243.1.207)
--> You do not have permissions to write to `/var/www/yable'. (162.243.1.207)
--> You do not have permissions to write to `/var/www/yable/releases'. (162.243.1.207)
--> `git' could not be found in the path (162.243.1.207)
这是我的 config/deploy.rb 文件：
set :application, "Yable.com"
set :scm, :git
set :repository, "git@github.com:Yable/yable-node-js.git"
set :user, "root"
set :ssh_options, { :forward_agent => true }
default_run_options[:pty] = true
set :use_sudo, false
set :branch, "master"
role :app, "162.243.1.207"
set :deploy_to, "/var/www/yable"
set :default_environment, {
'PATH' => "/var/www/yable",
'NODE_ENV' => 'production'
}
我傻眼了，因为提到的目录（/var/www/yable/releases）确实存在并且已经安装了 git。有任何想法吗？
谢谢，弗朗西斯
