1.git（用来下载vim和相关插件）

sudo apt-get install git

2,cmake（用来编译clang-llvm）

sudo apt-get install build-essential cmake

3.vim，这里手动编译vim，因为需要python支持，直接apt-get的话会遇到很多麻烦

过程参考 https://github.com/Valloric/YouCompleteMe/wiki/Building-Vim-from-source
先安装依赖项，注意，Ubuntu 16.04是 `liblua5.1-dev`而不是 `lua5.1-dev`

sudo apt-get install libncurses5-dev libgnome2-dev libgnomeui-dev \
    ibgtk2.0-dev libatk1.0-dev libbonoboui2-dev \
    libcairo2-dev libx11-dev libxpm-dev libxt-dev python-dev \
    python3-dev ruby-dev lua5.1 liblua5.1-dev libperl-dev git

4.验证安装

vim --version
查找到python，前面有加号即支持python

python3

注意：虽然 vim --version | grep python显示的python前面确实是加号, 但没有针对Ubuntu 16.04更改配置，导致vim支持还是没有安装。

所以个人认为。如果已经有vim的话还是移除它，重新安装

4.1移除：

sudo apt-get remove vim vim-runtime gvim
sudo apt-get remove vim-tiny vim-common vim-gui-common vim-nox

4.2配置：

cd ~
git clone https://github.com/vim/vim.git
cd vim
./configure --with-features=huge \
            --enable-multibyte \
            --enable-rubyinterp=yes \
            --enable-pythoninterp=yes \
            --with-python-config-dir=/usr/lib/python2.7/config-x86_64-linux-gnu \
            --enable-python3interp=yes \
            --with-python3-config-dir=/usr/lib/python3.5/config-3.5m-x86_64_linux-gnu \
            --enable-perlinterp=yes \
            --enable-luainterp=yes \
            --enable-gui=gtk2 --enable-cscope --prefix=/usr
make VIMRUNTIMEDIR=/usr/share/vim/vim81

4.3安装：

cd ~/vim
sudo make install

安装成功后，打开vim，命令模式下输入 :echo has("python") || has("python3")，结果是1就代表成功了。

4.4如果卸载的话相反的，需要保留vim文件夹并且安装checkinstall

sudo apt-get install checkinstall
cd ~/vim
sudo checkinstall

5.安装Vundle（用来管理vim插件）（类似于Python的pip）

5.1.安装：

git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim

5.2.创建并配置.vimrc配置文件

将配置文件添加到你的用户的home文件夹中：

sudo vim ~/vimrc

添加如下内容（大佬配置一）：

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'
Plugin 'Valloric/YouCompleteMe'
" 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)
Plugin 'file:///home/gmarik/path/to/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
filetype plugin indent on    " required
" To ignore plugin indent changes, instead use:
"filetype plugin on
"
