ruby-on-rails – 使用Apache乘客错误生产的Rails

We're sorry,but something went wrong.
We've been notified about this issue and we'll take a look at it shortly.

当在我的终端给出tail /var/log/apache2/error.log我得到这个：

/home/gre_stag/.rbenv/versions/2.2.2/lib/ruby/2.2.0/irb/ruby-lex.rb:230:in `catch'
  /home/gre_stag/.rbenv/versions/2.2.2/lib/ruby/2.2.0/irb/ruby-lex.rb:230:in `each_top_level_statement'

[ 2015-08-07 12:33:23.9794 4936/7f1db502e700 age/Cor/Req/CheckoutSession.cpp:252 ]: [Client 1-1] Cannot checkout session because a spawning error occurred. The identifier of the error is cfaf3a49. Please see earlier logs for details about the error.

在/etc/apache2/sites-available/depot.conf我有这个代码：

<VirtualHost *:80>
    PassengerRuby /home/gre_stag/.rbenv/versions/2.2.2/bin/irb
    ServerName depot.local
    ServerAlias www.depot.local
    ServerAdmin webmaster@localhost
    PassengerRoot /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini
    DocumentRoot /home/gre_stag/RoR/workspace/depot/public
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
    <Directory /home/gre_stag/RoR/workspace/depot/public>
        Options FollowSymLinks Includes ExecCGI
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

我不确定’PassengerRuby’的价值.
这是我第一次使用apache.我将不胜感激任何帮助.

UPDATE
