我试着安装通过打捆宝石linecache19，它总是返回：linecache19不会安装

显然，这看起来像我已经安装了红宝石的错误版本，但我知道一个事实，我有红宝石1.9.2安装：
[email protected]:/rails/gitlabhq$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-linux]
我试着手动安装gem工作没问题，但bundler仍然返回该输出并拒绝继续前进。
[email protected]:/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。
我没有安装在此服务器上的RVM或类似的东西，它只是使用系统红宝石和系统宝石库。
我有完全相同的问题。你有没有想过这个？ – knuton
