我在使用Ruby 1.9.3p327，RubyGems 1.8.23和Passenger 3的AWS Micro实例上。
我的服务器（当我没有尝试解决问题的时候）是http://shaanan.cohney.info/gitlab/
我正在尝试将Gitlab安装到Apache2上。
一切顺利，我尝试通过乘客部署安装。
我收到错误：
Could not find multi_json-1.5.0 in any of the sources (Bundler::GemNotFound)
/usr/local/lib/ruby/gems/1.9.1/gems/bundler-1.3.0/lib/bundler/spec_set.rb 95 in `block in materialize'
我打印的载入路径为：
["/usr/local/lib/ruby/gems/1.9.1/gems/passenger-3.0.19/lib", "/usr/local/lib/ruby/gems/1.9.1/gems/bundler-1.3.0/lib", "/usr/local/lib/ruby/site_ruby/1.9.1", "/usr/local/lib/ruby/site_ruby/1.9.1/x86_64-linux", "/usr/local/lib/ruby/site_ruby", "/usr/local/lib/ruby/vendor_ruby/1.9.1", "/usr/local/lib/ruby/vendor_ruby/1.9.1/x86_64-linux", "/usr/local/lib/ruby/vendor_ruby", "/usr/local/lib/ruby/1.9.1", "/usr/local/lib/ruby/1.9.1/x86_64-linux"]
缺少安装我的宝石的目录。
我在网上搜索过，但在尝试了多件事之后还没有找到解决办法。
访问myhostname.com/gitlab
时出现错误我目前的猜测是，它与我安装了ruby的用户，与应用程序的用户相比，与用户乘客正在运行的用户有关。
更新：我已升级到乘客的测试版，看它是否会有所作为。出错时，它给我的环境如下：
