换了一个系统， xubuntu14 ，然后今天安装 YCM 的时候出错了错误，我的安装指令是./install.py -all
msbuild or xbuild is required to build Omnisharp
后来查到了这篇回答，why-is-omnisharp-not-working，看到了 programingfrik 的答案，说是omnisharp没能正确安装，于是我切换到YouCompleteMe/third_party/ycmd/third_party/OmniSharpServer目录下，执行了一下安装指令
git checkout master
git submodule update --init --recursive
sudo apt-get install mono-xbuild
xbuild
然后又报错了，这回不知道该咋办了，特来向 V 友们求助！
我的分支和 mono 版本是这样的：
➜ /home/michael/Bundle/k-vim/bundle/YouCompleteMe/third_party/ycmd/third_party/OmniSharpServer (master) $ git branch -v

望 V 友们给个提示呗，这是啥错误啊，从哪里入手解决！

折腾了一下，决定不整了，记录一下我折腾的情况吧！
首先，发现自己装的时候装错了，我安装YCM的时候，用的是./install.py -all，这是默认安装所有特性，其中就包括了，C#的补全（./install.py --omnisharp-completer）而报错的这个OmniSharpServer库，正是C#的补全库！，什么鬼，Linux下写C#这种事情我根本不会干好伐！
但是觉得已经开搞了，不试着解决解决总是怪怪的，于是找了一下解决方案，发现我少装了两个包，又装了这么两个包 ！
sudo apt-get install libmono-microsoft-build-tasks-v4.0-4.0-cil
sudo apt-get install mono-dmcs

但是还是报错啊，错误是这样的：
/home/michael/Bundle/k-vim/bundle/YouCompleteMe/third_party/ycmd/third_party/OmniSharpServer/OmniSharp.sln (default targets) ->
(Build target) ->
/home/michael/Bundle/k-vim/bundle/YouCompleteMe/third_party/ycmd/third_party/OmniSharpServer/OmniSharp/OmniSharp.csproj (default targets) ->
/usr/lib/mono/4.5/Microsoft.CSharp.targets (CoreCompile target) ->
: error CS8001: Warning as Error: SDK path could not be resolved
然后我就无解了，最终决定放弃，因为我根本不会在VIM中写C#啊，感觉自己真是闲的蛋疼！
