【问题描述】：

我第一次尝试在 vexxhost 上部署我的 rails 应用程序。我使用 github 作为我的源代码管理和 capistrano。

这是我的部署文件

   require 'bundler/capistrano'
   require 'capistrano'
   require 'bundler'
   require 'capistrano-vexxhost'

   # Account Settings

   ssh_options[:forward_agent] = true
   set :scm_command, "/home/user/opt/bin/git"
   set :local_scm_command,"git"
   set :user, "xxxxxxxx"
   set :password, "xxxxxxxxx"
   set :domain, "domain.com"
   set :mount_path,"/home/xxxxxxxx/xxxxxxx"
   set :application,"app name"
   set :scm, :git
   set :deploy_via, :copy
   set :repository, "git@github.com:xxxxx/xxxxxxx.git"
   default_run_options[:pty] = true

问题 1)

当我安装 gem 'capistrano' gem 'capistrano-vexxhost' 时，我在尝试在本地运行我的应用程序时遇到了以下错误（它在安装 capistrano 之前正在工作）。

 C:/Ruby193/lib/ruby/gems/1.9.1/gems/capistrano-2.14.1/lib/capistrano/configuration/loading.rb:18:in `instance': Please require this file from within a Capistrano recipe (LoadError)

    from script/rails:6:in `require'
    from script/rails:6:in `<main>'

注意但是，当我在 application.rb 文件中的以下代码中注释 Bundler.require 行时，它会成功运行，但无法识别宝石

  if defined?(Bundler)
  # If you precompile assets before deploying to production, use this line
  Bundler.require(*Rails.groups(:assets => %w(development test)))
  # If you want your assets lazily compiled in production, use this line
  # Bundler.require(:default, :assets, Rails.env)
  end

问题 2) 什么时候在我的 ruby 命令提示符上键入“cap deploy:check”我得到以下错误。

问题 3) 什么时候在我的 ruby 命令提示符下键入“cap deploy:cold”我收到以下错误

我的 deploy.rb 中是否缺少任何内容，或者有什么我没有做的。

请帮助我，我已经解决这个问题很长时间了。我是部署 Web 应用程序的新手，而且 Rails 对我来说非常困难

请帮忙

【解决方案1】：

问题 2 和 3 您的第二个和第三个问题是 git 和 tar 不在您的路径中的结果。要么根本没有安装它们，要么你的路径不完整。请参阅我在下面引用的错误。

问题 2

 'git' could not be found on the local host
 'tar' could not be found on the local host

问题 3

 no such file or directory git ls-remote...

问题 1

很遗憾，我对#1 没有答案。猜测是您需要将capistrano 和/或capistrano-vexxhost 添加到您的deploy.rb。
