我试图在我的VPS上部署我的第一个Rails 3.x应用程序，但这并不是很成功。在我的VPS我使用Apache和乘客，但是当我启动应用程序，我得到这样的错误：使用RVM所需的Ruby版本无法启动Rails应用程序？
/var/www/my_domain_name/sample_app/config/initializers/wrap_parameters.rb:8: syntax error, unexpected ':', expecting kEND wrap_parameters format: [:json]^

我想通了，这个问题可能是错误的Ruby版本，因为1.8.7不能正确识别一些散列语法。但这很奇怪，因为它不应该使用预装的Ruby 1.8.7，而是1.9.3。在我的CentOS 6.2我安装RVM和Ruby 1.9.3，所以我有这样的：
ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]
rvm list
rvm rubies
=* ruby-1.9.3-p194 [ x86_64 ]
# => - current
# =* - current && default
# * - default
所以这是奇怪的是，我得到：
sudo ruby -v
ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]
这就是为什么我认为，由于某种原因，旅客选秀权错误的Ruby版本。当我尝试启动服务器时，如：
rails server
它的工作原理和我可以通过MY_IP：3000访问我的应用程序没有任何问题。
所以问题是：我如何让Passenger加载需要的Ruby版本，而不是预装的？
这就是Apache的error_log的尾巴重新启动后：

你会如此善良，写更多细节我必须做什么？我在部署应用程序后运行了bundle install。我也尝试过运行bundle exec install，但那样就犯了错误。 – kovpack 2012-07-24 17:01:01
您用来运行乘客的命令是什么？我使用精简而不是命令来启动瘦是捆绑exec瘦启动-C thin.yml。用您的乘客启动命令替代[命令]。 – Bryan 2012-07-24 18:07:48
它自动启动（我使用Apache的乘客）。 – kovpack 2012-07-24 18:58:17
