ruby-on-rails - 由于 bundle 程序错误 : "An error occurred while installing json...",，Capistrano 无法部署，但我可以手动安装

Question

我是 Rails 和 capistrano 新手，今天一整天我都在努力让所有这些东西正常工作。

现在我有一个问题，我根本不知道如何解决。

症状:

cap staging deploy

... lots of stuff goes here and then...

The deploy has failed with an error: Exception while executing as rreimche@my-server.com: bundle exit status: 5

但是当我以 rreimche 身份登录并执行“gem install json -v 1.8.2”时——一切正常。然后我尝试将整个失败的命令作为 rreimche 运行，它运行得非常完美:(我已经从命令末尾删除了“--quite”，假设它只是使运行不冗长)

set :application, 'kariera-centr.ru'
set :repo_url, 'https://github.com/mygit/myrepo.git' 

namespace :deploy do

  after :restart, :clear_cache do

    end
  end

end

分期.rb

我的本地系统是 Mac OS X 10.8。

如果有任何帮助，我将不胜感激。谢谢你。
