Question

首先，我在ubuntu上使用rvm 1.15.8（稳定版）通过wayne开发app rails，我将部署到我的vps。

以下是我的vps上构建rails应用程序的历史记录：

在我的vps上使用用户“user”安装rvm，我试用了this，这里是rvm info

[user@myhost ~]$ rvm info

ruby-1.9.3-p392:

我在我的vps上使用kloxo控制面板，目录root位于/home/admin/myapp/public
我将部署，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

    '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，我收到了错误

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"

你能帮我纠正一下我的步骤和代码吗？

Answer 1

尝试将rvm-capistrano的require移动到文件末尾。我最近也这样做了。

当你使用rvm时，你不需要设置bundle cmd，bundle_dir或default_environment（除非你为其他东西做这件事吗？

看起来您似乎正在尝试检测本地用于部署的ruby版本，为此set :rvm_ruby_string, :local就是您所需要的

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）

无法使用RVM Capistrano部署应用程序
