我试图通过bundler安装gem linecache19，它总是返回：

显然看起来我安装了错误版本的ruby，但我知道我安装了ruby 1.9.2：
me@host:/rails/gitlabhq$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-linux]
我尝试手动安装没有问题的gem，但是Bundler仍然返回该输出并拒绝继续前进。
me@host:/rails/gitlabhq$ sudo gem install linecache19
Building native extensions. This could take a while...
Successfully installed linecache19-0.5.12
1 gem installed
我不确定为什么bundler没有安装gem /没有在系统gem库中看到它。
我没有在此服务器上安装RVM或类似的东西，它只使用系统ruby和系统gem库。
