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:

其中 libruby1.8.so.1.8 => not found

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)
    libruby.so.2.0 => /home/zhanghb/.rvm/rubies/ruby-2.0.0-p247/bin/../lib/libruby.so.2.0 (0x00007f89188d9000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f89184f4000)
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f89182d6000)
    librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f89180ce000)
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f8917ec9000)
    libcrypt.so.1 => /lib/x86_64-linux-gnu/libcrypt.so.1 (0x00007f8917c90000)
    libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f891798a000)
    /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)
    libacl.so.1 => /lib/x86_64-linux-gnu/libacl.so.1 (0x00007f6d183a8000)
    libgpm.so.2 => /usr/lib/x86_64-linux-gnu/libgpm.so.2 (0x00007f6d181a1000)
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f6d17f9c000)
    libpython2.7.so.1.0 => /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0 (0x00007f6d17a35000)
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f6d17817000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f6d17450000)
    libpcre.so.3 => /lib/x86_64-linux-gnu/libpcre.so.3 (0x00007f6d17212000)
    /lib64/ld-linux-x86-64.so.2 (0x00007f6d18d0b000)
    libattr.so.1 => /lib/x86_64-linux-gnu/libattr.so.1 (0x00007f6d1700d000)
    libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f6d16df3000)
    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?
