Ubuntu16.04安装vim8
在Ubuntu16.04下编译安装vim8，并配置vim-plug插件管理器，以及安装YouCompleteMe等插件。
安装依赖
sudo apt-get install libncurses5-dev libgnome2-dev libgnomeui-dev \
libgtk2.0-dev libatk1.0-dev libbonoboui2-dev \
libcairo2-dev libx11-dev libxpm-dev libxt-dev python-dev \
python3-dev ruby-dev liblua5.1 lua5.1-dev libperl-dev git需要注意的是在Ubuntu16.04中Lua应该为liblua5.1-dev，而在其它版本中应为lua5.1-dev
删除已有vim相关包
dpkg -l | grep vim
sudo apt remove vim vim-common vim-runtime vim-tiny下载最新vim并编译安装
git clone https://github.com/vim/vim.git
./configure --with-features=huge \
--enable-multibyte \
--enable-rubyinterp=yes \
--enable-pythoninterp=yes \
--with-python-config-dir=/usr/lib/python2.7/config \
--enable-perlinterp=yes \
--enable-luainterp=yes \
--enable-gui=gtk2 --enable-cscope --prefix=/usr
make VIMRUNTIMEDIR=/usr/share/vim/vim80 -j5
sudo make install配置vim
不配置vim的话会比较难用，增加一些插件和个人习惯性的定制能提升编码效率。
在下载安装vim插件这件事儿上，Vundle很慢，基于异步的vim-plug则非常快。上手吧：
" Specify a directory for plugins
" - For Neovim: ~/.local/share/nvim/plugged
" - Avoid using standard Vim directory names like 'plugin'
call plug#begin('~/.vim/plugged')
" Make sure you use single quotes
" Shorthand notation; fetches https://github.com/junegunn/vim-easy-align
Plug 'junegunn/vim-easy-align'
" Any valid git URL is allowed
Plug 'https://github.com/junegunn/vim-github-dashboard.git'
" Multiple Plug commands can be written in a single line using | separators
Plug 'SirVer/ultisnips' | Plug 'honza/vim-snippets'
" On-demand loading
Plug 'scrooloose/nerdtree', { 'on': 'NERDTreeToggle' }
Plug 'tpope/vim-fireplace', { 'for': 'clojure' }
" Using a non-master branch
Plug 'rdnetto/YCM-Generator', { 'branch': 'stable' }
" Using a tagged release; wildcard allowed (requires git 1.9.2 or above)
Plug 'fatih/vim-go', { 'tag': '*' }
" Plugin options
Plug 'nsf/gocode', { 'tag': 'v.20150303', 'rtp': 'vim' }
" Plugin outside ~/.vim/plugged with post-update hook
Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' }
Plug 'Valloric/YouCompleteMe', { 'do': './install.py' }
" Unmanaged plugin (manually installed and updated)
Plug '~/my-prototype-plugin'
" Initialize plugin system
call plug#end()
"" 个人定制的一些配置，不喜欢、不习惯可以自行修改
set nu
set tags=./.tags;.tags
set cursorline
set showmatch
set hlsearch
set incsearch
hi CursorLine cterm=NONE ctermbg=black ctermfg=green guibg=NONE guifg=NONE关闭vim，再次vim ~/.vimrc，敲入:PlugInstall，开始下载插件：可以看到各个插件是同时在下载的，速度很快。
其中YouCompleteMe因为有很多submodule，很容易下载失败，所以手动处理一下：
cd ~/.vim/plugged/YouCompleteMe
git submodule update --init --recursive
python install.py
