也忘记自己当初做了什么, 升级到了 Ubuntu14.04以后, Vim 打开不了了.出现的错误是:
vim: error while loading shared libraries: libruby1.8.so.1.8: cannot open shared object file: No such file or directory
ldd 了一下 vim. 结果是:

然后我查看了一下 ruby 的依赖.
➜ ~ ldd /home/zhanghb/.rvm/rubies/ruby-2.0.0-p247/bin/ruby
linux-vdso.so.1 => (0x00007fff05597000)

/lib64/ld-linux-x86-64.so.2 (0x00007f8918d57000)
其中有一个 libruby.so.2.0
这还不是最后的问题, 问题是我登上自己的 linode 服务器, 也是 ubuntu14.04, 但是 ldd vim 以后 发现和本地机器的结果根本不一样. 结果是:
➜ ~ ldd /usr/bin/vim
linux-vdso.so.1 => (0x00007fff9dec8000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f6d189fd000)
libtinfo.so.5 => /lib/x86_64-linux-gnu/libtinfo.so.5 (0x00007f6d187d4000)
libselinux.so.1 => /lib/x86_64-linux-gnu/libselinux.so.1 (0x00007f6d185b0000)

libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f6d17817000)

libutil.so.1 => /lib/x86_64-linux-gnu/libutil.so.1 (0x00007f6d16bf0000)
所以, 为什么会缺失了 libruby1.8.so.1.8 , 还有 ,linode 上面和我本地机器的 vim 依赖为什么差别这么多呢?
编译方式不一样？
试下vim --version看看，建议重新编译下Vim，这样它依赖的应该就是系统自带的libruby了。
BTW，获取系统自带的libruby的方法：find /usr/lib -name 'libruby*'
