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。

vim下python 的配置

其他 Python Vim

由于最近要做数字图像处理的大作业，以及之后一段时间，估计写python多一些，所以打算花些时间配置下vim. # 1. 一键执行 # 其实之前一直有的。。不过没有效果，就没有管。发现问题是，python对应的filetype为"python"，而不是"py" # 1func!
