安装插件需要有一个插件管理器。此处使用的是Vundle

下载地址：https://github.com/VundleVim/Vundle.vim.git

1、vim安装到/usr/local/vim目录下，vimrc在/usr/local/vim/share/vim/中

vimrc可以使用此处的，或者在用户目录下新建一个.vimrc使用，此处就直接使用默认的vimrc

创建插件目录：

mkdir -p /usr/local/vim/share/vim/bundle

2、配置YouCompleteMe

# cd /usr/local/vim/share/vim/bundle/YouCompleteMe

# python install.py –clang-completer –go-completer

3、此处用到powerline，下面是安装步骤：

1、用pip安装
pip3 install powerline-status

2、查看并记录location位置
pip3 show powerline-status
......
Location: /usr/local/python/lib/python3.5/site-packages
......

3、配置powerline到bash（此处可选，如果喜欢可以配置）
在~/.bashrc中添加
powerline-daemon -q
POWERLINE_BASH_CONTINUATION=1
POWERLINE_BASH_SELECT=1
. /usr/local/python/lib/python3.5/site-packages/powerline/bindings/bash/powerline.sh
重载bashrc
source ~/.bashrc
在bashrc中加这些以后重新启动终端如果报错可以加几个映射：
ln -s /usr/local/python/bin/powerline /usr/local/bin
ln -s /usr/local/python/bin/powerline-config /usr/local/bin
ln -s /usr/local/python/bin/powerline-daemon /usr/local/bin

3、此处主要是在vim中使用powerline样式，需要在vimrc中添加如下设置
set rtp+=/usr/local/python/lib/python3.5/site-packages/powerline/bindings/vim
set laststatus=2
set t_Co=256

4、记录几个常用插件配置
