我正在按照此处的指南将 Redmine 安装到 Tomcat，但我在运行 Warbler 时遇到了问题。当我尝试跑步时
ruby /var/lib/gems/1.8/gems/warbler-1.2.1/bin/warble config
我收到这个错误
/var/lib/gems/1.8/gems/warbler-1.2.1/bin/warble:10:in `require': no such file to load -- warbler (LoadError)
from /var/lib/gems/1.8/gems/warbler-1.2.1/bin/warble:10
我四处搜寻，发现这是由于不需要 rubygems 造成的。当我尝试解决此问题并运行时
ruby -rubygems /var/lib/gems/1.8/gems/warbler-1.2.1/bin/warble config
我现在遇到这个错误
warble aborted!
no such file to load -- /var/lib/gems/1.8/gems/jruby-rack-1.0.5/lib/jruby-rack-1.0.5.jar
/usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'
当我使用 --trace 运行最后一个命令时，我得到了这个
warble aborted!

该文件/var/lib/gems/1.8/gems/jruby-rack-1.0.5/lib/jruby-rack-1.0.5.jar存在，所以我不确定它为什么会遇到问题。
这是 的输出gem list，以防万一它有用。
