manjaro(archlinux) 安装 YouCompleteMe

来来回回折腾了好多次，aur直接安装或者手动编译，安装后都无法补全

ycm的log文件是在/tmp目录下的。

发现问题是缺少libtinfo.so.5

解决办法：

 sudo pacman-key --refresh-keys
 gpg --keyserver pgp.mit.edu --recv-keys C52048C0C0748FEE227D47A2702353E0F7E48EDB
 yaourt -S libtinfo5

参考a资料

比较诡异的是，我把vim配置删掉，就可以补全，以至于之前一直以为是ycm和配置文件中的某个内容冲突。
