在 capistrano 部署上找不到 rake
因此，我尝试使用 RVM 通过 nginx/unicorn 服务器获取 capistrano 部署设置。
部署工作正常，但是当我尝试通过 capistrano 与 unicorn 交互时，我收到如下错误：
[~/source/quibbler/config]
$ cap unicorn:start
* executing `unicorn:start'
* executing "cd /u/apps/quibbler/current && bundle exec unicorn_rails -c /u/apps/quibbler/current/config/unicorn-production.rb -E production -D"
servers: ["wwwtestvm.whf.app"]
[wwwtestvm.whf.app] executing command
** [out :: wwwtestvm.whf.app] Could not find rake-0.9.2 in any of the sources
command finished in 553ms
failed: "rvm_path=/usr/local/rvm /usr/local/rvm/bin/rvm-shell 'ruby-1.9.2-p290@quibbler' -c 'cd /u/apps/quibbler/current && bundle exec unicorn_rails -c /u/apps/quibbler/current/config/unicorn-production.rb -E production -D'" on wwwtestvm.whf.app
我整夜搜索了互联网，但找不到解决方案。如果我将命令复制粘贴到 shell 中，它就会起作用，因此我 99% 确定它与 RVM 环境不正确有关。
我已经创建了部署和独角兽配置的要点：

任何帮助或 将不胜感激。
So I am attempting to get a capistrano deployment setup with an nginx/unicorn server, using RVM.
The deploy works, but when I attempt to interact with unicorn via capistrano i get an error like:
[~/source/quibbler/config]
$ cap unicorn:start
* executing `unicorn:start'
* executing "cd /u/apps/quibbler/current && bundle exec unicorn_rails -c /u/apps/quibbler/current/config/unicorn-production.rb -E production -D"
servers: ["wwwtestvm.whf.app"]
[wwwtestvm.whf.app] executing command
** [out :: wwwtestvm.whf.app] Could not find rake-0.9.2 in any of the sources
command finished in 553ms
failed: "rvm_path=/usr/local/rvm /usr/local/rvm/bin/rvm-shell 'ruby-1.9.2-p290@quibbler' -c 'cd /u/apps/quibbler/current && bundle exec unicorn_rails -c /u/apps/quibbler/current/config/unicorn-production.rb -E production -D'" on wwwtestvm.whf.app
I have searched the interwebs all night and can not find the solution. If I copy paste the command into my shell it works so I am 99% sure it has to do with the RVM environment not being correct.
I have created a gist of my deploy and unicorn configs:
https://gist.github.com/1375736#file_deploy.rb
https://gist.github.com/1375736#file_unicorn_production.rb
Any help or guidance would be appreciated.

感谢 sannankhalid 对此的回答 其他问题我能够解决它。
简短的回答：将 rake 添加到您的 Gemfile，确保运行
bundle install以便更新您的 Gemfile.lock，然后部署到您的服务器，耶！Thanks to sannankhalid answer on this other question i was able to resolve it.
Short answer: add rake to your Gemfile, make sure you run
bundle installso your Gemfile.lock gets updated, then deploy to your server, ayay!
