Question

我正在尝试配置Capistrano将我的OS X系统中的Rails 3.2.14应用程序部署到CentOS 6 VPS。

我在两台机器上都有RVM gemsets，名为“ruby-1.9.3@rails_3_personal”。

我安装了capistrano和rvm / capistrano宝石。

我确保登录用户在目标服务器上具有所需的目录权限。

当我跑...

cap deploy:setup -d

我得到了这个输出......

为什么Capistrano会尝试创建/ruby-1.9.3-p448？

这个错误是什么意思？（另外两个喜欢吗？）路径甚至不是有效路径（“//”）。

     ** [out :: user_name@my_domain.com] /home/user_name/.rvm//scripts/selector: line 709: /db: No such file

此外......“Error: RVM was unable to use 'ruby-1.9.3-p448@rails_3_personal'”

好的，“无法使用。”为什么呢？我该如何解决？

这是我的deploy.rb ...

require "bundler/capistrano"

require "rvm/capistrano"

set :rvm_ruby_string, 'ruby-1.9.3-p448@rails_3_personal'

set :rvm_type, :user

set :application, 'my_app'

set :repository, 'git@github.com:GithubUser/my_app.git'

set :deploy_to, "/opt/deployed_rails_apps/#{application}"

set :use_sudo, false

set :scm, "git"
set :branch, "master"

set :user, 'user_name'

set :deploy_via, :remote_cache

# Keep only 5 releases --------------------------------
set :keep_releases, 5
after "deploy:update", "deploy:cleanup"
# -----------------------------------------------------

load 'deploy/assets'

role :app, 'user_name@my_domain.com'
role :web, 'user_name@my_domain.com'

namespace :deploy do

  task :start, :roles => :app do
    run "touch #{current_release}/tmp/restart.txt"
  end

  task :stop, :roles => :app do
    # Do nothing.
  end

  desc "Restart Application"
  task :restart, :roles => :app do
    run "touch #{current_release}/tmp/restart.txt"
  end

end

Answer 1

我认为问题实际上是这个脚本：

 ** [out :: user_name@my_domain.com] /home/user_name/.rvm//scripts/selector: line 709: /db: No such file or directory

似乎在你的require "rvm/capistrano"中调用了女巫。您可以尝试对其进行注释并手动设置路径：

set :default_environment, {
    'PATH' => PATH,
    'GEM_HOME'     => GEM_HOME,
    'GEM_PATH'     => GEM_PATH,
}

要查看您的值，您可以在切换到gemset后看到rvm info。

Answer 2

这是一个错误，并通过https://github.com/wayneeseguin/rvm/issues/2186

修复

需要在服务器上更新到最新版本的rvm：

rvm get head

这个Capistrano错误输出是什么意思？
