安装vim 的扩展管理插件
Vundle是一款Vim的插件管理软件(Linux)，用起来很方便的原因有几点：
- 支持插件超多，可以来源于github、Vundle自带、Vim-scripts、本地仓库等等。
- 安装流程非常简单，配置好vimrc后一键安装/更新所有
- Vundle很容易上手，很方便
下载vundle到指定位置
$ git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
添加如下配置文件
set nocompatible " be iMproved, required
filetype off " required
" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
" alternatively, pass a path where Vundle should install plugins
"call vundle#begin('~/some/path/here')
" let Vundle manage Vundle, required
Plugin 'VundleVim/Vundle.vim'
" The following are examples of different formats supported.
" Keep Plugin commands between vundle#begin/end.
" plugin on GitHub repo
Plugin 'tpope/vim-fugitive'
" plugin from http://vim-scripts.org/vim/scripts.html
" Plugin 'L9'
" Git plugin not hosted on GitHub
Plugin 'git://git.wincent.com/command-t.git'
" git repos on your local machine (i.e. when working on your own plugin)
" The sparkup vim script is in a subdirectory of this repo called vim.
" Pass the path to set the runtimepath properly.
Plugin 'rstacruz/sparkup', {'rtp': 'vim/'}
" Install L9 and avoid a Naming conflict if you've already installed a
" different version somewhere else.
" Plugin 'ascenator/L9', {'name': 'newL9'}
" All of your Plugins must be added before the following line
call vundle#end() " required

" To ignore plugin indent changes, instead use:
"filetype plugin on
"
