Redmine和backlog没有这样的文件加载 - phusion_passenger/utils（LoadError）

Question

我试图安装redmine with backlog插件。我跟着这个教程：https://github.com/backlogs/redmine_backlogs/wiki/Installation-of-Backlogs-in-Redmine-2.0

现在我有Apache的错误：

/usr/lib/phusion_passenger/passenger-spawn-server:53:in `require': no such file to load -- phusion_passenger/utils (LoadError) 
     from /usr/lib/phusion_passenger/passenger-spawn-server:53:in `<main>' 
[ pid=4064 file=ext/apache2/Hooks.cpp:725 time=2012-09-16 23:23:45.726 ]: 
    Unexpected error in mod_passenger: Cannot spawn application '/var/www/redmine': The spawn server has exited unexpectedly. 
    Backtrace: 
    in 'virtual boost::shared_ptr<Passenger::Application::Session> Passenger::ApplicationPoolServer::Client::get(const Passenger::PoolOptions&)' (ApplicationPoolServer.h:471) 
    in 'int Hooks::handleRequest(request_rec*)' (Hooks.cpp:521) 

这是我的虚拟主机配置：

<VirtualHost *:80> 
    ServerName redmine.my.domain 
    DocumentRoot "/var/www/redmine/public" 

    <Directory "/var/www/redmine/public/"> 
    RailsBaseURI /redmine 
    PassengerResolveSymlinksInDocumentRoot on 
    </Directory> 
</VirtualHost> 

我的/ etc/apache2的/ MODS的可用/乘客。 CONF

<IfModule mod_passenger.c> 
    PassengerRoot /usr 
    PassengerRuby /usr/bin/ruby 
    PassengerDefaultUser www-data 
</IfModule> 

更多：

/usr/bin/ruby -> /etc/alternatives/ruby 
/etc/alternatives/ruby -> /usr/bin/ruby1.9.1 

ruby -v 
ruby 1.9.1p378 (2010-01-10 revision 26273) [x86_64-linux] 

任何想法？

你看这个问题的提示：Rails application doesn't work with apache2 and passenger？ （它看起来像是相同类型的错误）。一个人安装了几个版本的Ruby，这导致了问题。

希望它会有所帮助。
