无法使用 RVM Capistrano 部署应用程序

Question

首先，我在 ubuntu 上使用 wayne 的 rvm 1.15.8（稳定版）开发应用程序轨，我将部署到我的 vps。

这是在我的 vps 上构建 rails 应用程序的历史：

1. 在我的 vps 上使用用户“user”安装 rvm，我从 this 尝试过，这里是 rvm info

   [user@myhost ~]$ rvm info
   
   ruby-1.9.3-p392:
   
     system:
       uname:       "Linux mydomain.com 2.6.32-358.6.1.el6.i686 #1 SMP Tue Apr 2
   3 18:13:20 UTC 2013 i686 i686 i386 GNU/Linux"
       system:      "centos/6.4/i386"
       bash:        "/bin/bash => GNU bash, version 4.1.2(1)-release (i386-redhat-l
   inux-gnu)"
       zsh:         " => not installed"
   
     rvm:
       version:      "rvm 1.19.6 (stable) by Wayne E. Seguin <wayneeseguin@gmail.co
   m>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]"
       updated:      "16 hours 9 minutes 44 seconds ago"
   
     ruby:
       interpreter:  "ruby"
       version:      "1.9.3p392"
       date:         "2013-02-22"
       platform:     "i686-linux"
       patchlevel:   "2013-02-22 revision 39386"
       full_version: "ruby 1.9.3p392 (2013-02-22 revision 39386) [i686-linux]"
   
     homes:
       gem:          "/usr/local/rvm/gems/ruby-1.9.3-p392"
       ruby:         "/usr/local/rvm/rubies/ruby-1.9.3-p392"
   
     binaries:
       ruby:         "/usr/local/rvm/rubies/ruby-1.9.3-p392/bin/ruby"
       irb:          "/usr/local/rvm/rubies/ruby-1.9.3-p392/bin/irb"
       gem:          "/usr/local/rvm/rubies/ruby-1.9.3-p392/bin/gem"
       rake:         "/usr/local/rvm/gems/ruby-1.9.3-p392/bin/rake"
   
     environment:
       PATH:         "/usr/local/rvm/gems/ruby-1.9.3-p392/bin:/usr/local/rvm/gems/r
   uby-1.9.3-p392@global/bin:/usr/local/rvm/rubies/ruby-1.9.3-p392/bin:/usr/local/r
   vm/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/user/bin"
       GEM_HOME:     "/usr/local/rvm/gems/ruby-1.9.3-p392"
       GEM_PATH:     "/usr/local/rvm/gems/ruby-1.9.3-p392:/usr/local/rvm/gems/ruby-
   1.9.3-p392@global"
       MY_RUBY_HOME: "/usr/local/rvm/rubies/ruby-1.9.3-p392"
       IRBRC:        "/usr/local/rvm/rubies/ruby-1.9.3-p392/.irbrc"
       RUBYOPT:      ""
       gemset:       ""
   

2. 我正在为我的 vps 使用 kloxo 控制面板，其根目录位于 /home/admin/myapp/public

3. 我会部署，这里是deploy.rb

require "bundler/capistrano"
require "rvm/capistrano"

server "xxx.xxx.xxx.xxx", :web, :app, :db, primary: true

set :bundle_cmd, "/usr/local/rvm/gems/ruby-1.9.3-p392@global"
set :bundle_dir, "/usr/local/rvm/gems/ruby-1.9.3-p392"
set :rvm_ruby_string, EVN['GEM_HOME'].gsub(/.*\?/,"")
set :rvm_type, :user

set :default_environment, { 
    'PATH' => "/usr/local/rvm/gems/ruby-1.9.3-p392/bin:/usr/local/rvm/gems/r
uby-1.9.3-p392@global/bin:/usr/local/rvm/rubies/ruby-1.9.3-p392/bin:/usr/local/r
vm/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/user/bin",
    'RUBY_VERSION' => 'ruby 1.9.3',
    'GEM_HOME' => "/usr/local/rvm/gems/ruby-1.9.3-p392",
    'GEM_PATH' => "/usr/local/rvm/gems/ruby-1.9.3-p392:/usr/local/rvm/gems/ruby-
1.9.3-p392@global",
    'BUNDLE_PATH' => "/usr/local/rvm/gems/ruby-1.9.3-p392"
}

set :application, "myapp"
set :user, "user"
set :deploy_to, "/home/admin/#{application}"
set :deploy_via, :remote_cache
set :use_sudo, false

set :scm, "git"
set :repository, "git@github.com:myuser/#{application}.git"
set :branch, "master"

default_run_options[:pty] = true
ssh_options[:forward_agent] = true
after "deploy", "deploy:cleanup" # keep only the

我尝试运行cap deploy:setup，但出现错误

executing "mkdir -p /home/admin/myapp /home/admin/myapp/release /home/admin/myapp/shared /home/admin/myapp/shared/system /home/admin/myapp/shared/log /home/admin/myapp/shared/pids"
   servers: ["xxx.xxx.xxx.xx"]

failed : "env PATH: .........etc"

您能帮我更正我的步骤和代码吗？

Answer 1

尝试将 rvm-capistrano 的要求移至文件末尾。我最近也这样做了。

当您使用 rvm 时，您不需要设置 bundle cmd、bundle_dir 或 default_environment（除非您这样做是为了其他目的？

您似乎也在尝试检测您在本地使用的 ruby​​ 版本，以便在部署中使用，只需 set :rvm_ruby_string, :local 即可

Answer 2

对我来说，

set :rvm_ruby_string, :local #doesn't work

没用。我不得不使用显式版本：

set :rvm_ruby_string, "2.1.2" #works

• capistrano (2.15.5)
• rvm-capistrano (1.5.2)
