我在 Apache 网络服务器上安装了 Passanger mod 并尝试运行我的应用程序（一个使用Rails 3.2.8和Ruby 1.9.3-p194）。

首先，我遇到了“bundler找不到宝石”之类的错误。搜索了一下我找到了一个解决方案 - 我只需要将GEM_PATH环境变量添加到我的虚拟主机。

但后来我遇到了另一个问题：几乎每个 gem 都会抛出这样的异常（Apache 错误日志）：

Rack: /home/shybovycha/projects/rails/blog: symbol lookup error: /usr/local/lib/ruby/gems/1.9.1/gems/json-1.7.5/lib/json/ext/parser.so: undefined symbol: rb_intern2
*** Exception EOFError in spawn manager (Unexpected end-of-file detected.) (process 31821):

  Unexpected error in mod_passenger: Cannot spawn application '/home/shybovycha/projects/rails/blog': The spawn server has exited unexpectedly.
  Backtrace:
     (empty)

尝试重新安装 gems，有和没有--platform选项给我什么。

注意： rails server完美进行。

请帮我解决这个问题！
