YouCompleteMe这个Vim插件还真不好安装，挺多坑的，折腾了挺久终于最后用上了。

测试环境：

[broly@localhost ~]$ cat /etc/redhat-release 
CentOS Linux release 7.4.1708 (Core)

1 2	[broly@localhost ~]$ cat /etc/redhat-release CentOS Linux release 7.4.1708 (Core)

一、更新Vim

我安装这个插件的时候，提示：YouCompleteMe unavailable : YouCompleteMe unavailable: requires Vim 7.4.1578+

所以不得不把系统自带的Vim更新到8.0

# 移除旧版本
sudo yum remove vim -y
# 安装必要组件
sudo yum install ncurses-devel python-devel -y
# 下载源码编译安装
git clone https://github.com/vim/vim.git
cd vim/src
# 根据自己实际情况设置编译参数
./configure --with-features=huge --enable-pythoninterp=yes --enable-cscope --enable-fontset --with-python-config-dir=/usr/lib64/python2.7/config
make
sudo make install

# 移除旧版本

sudo yum remove vim -y

# 安装必要组件

sudo yum install ncurses-devel python-devel -y

# 下载源码编译安装

git clone https://github.com/vim/vim.git

cd vim/src

# 根据自己实际情况设置编译参数

./configure --with-features=huge --enable-pythoninterp=yes --enable-cscope --enable-fontset --with-python-config-dir=/usr/lib64/python2.7/config

make

sudo make install

编译参数说明：
--with-features=huge：支持最大特性
--enable-rubyinterp：打开对ruby编写的插件的支持
--enable-pythoninterp：打开对python编写的插件的支持
--enable-python3interp：打开对python3编写的插件的支持
--enable-luainterp：打开对lua编写的插件的支持
--enable-perlinterp：打开对perl编写的插件的支持
--enable-multibyte：打开多字节支持，可以在Vim中输入中文
--enable-cscope：打开对cscope的支持
--with-python-config-dir=/usr/lib64/python2.7/config 指定python 路径
--with-python-config-dir=/usr/lib64/python3.5/config 指定python3路径

注意：必须带上Python编写插件支持，最好带上Python路径，否则使用时会报这个错误：YouCompleteMe unavailable: requires Vim compiled with Python (2.6+ or 3.3+) support

编译安装好Vim后，默然是安装在/usr/local/bin目录下，所以把该目录加入到PATH方便terminal全局使用：

sudo nano /etc/profile

1	sudo nano /etc/profile

在尾部添加：

export PATH=$PATH:/usr/local/bin/vim

1	export PATH=$PATH:/usr/local/bin/vim

然后使环境变量生效：

source /etc/profile

1	source /etc/profile

二、安装Vundle和YouCompleteMe

Vundle是Vim的插件管理工具，官方文档：https://github.com/VundleVim/Vundle.vim

安装步骤很简单：

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

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

编辑配置文件

vim ~/.vimrc

1	vim ~/.vimrc

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)
"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'}

Bundle 'altercation/vim-colors-solarized'
Plugin 'vim-scripts/OmniCppComplete'
Plugin 'Valloric/YouCompleteMe'

" 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
"
" Brief help
" :PluginList       - lists configured plugins
" :PluginInstall    - installs plugins; append `!` to update or just :PluginUpdate
" :PluginSearch foo - searches for foo; append `!` to refresh local cache
" :PluginClean      - confirms removal of unused plugins; append `!` to auto-approve removal
"
" see :h vundle for more details or wiki for FAQ
" Put your non-Plugin stuff after this line

syntax enable
colorscheme monokai

let g:ycm_global_ycm_extra_conf='~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/ycm/.ycm_extra_conf.py'

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'

"Plugin 'file:///home/gmarik/path/to/plugin'

" The sparkup vim script is in a subdirectory of this repo called vim.

"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'}

Bundle 'altercation/vim-colors-solarized'

Plugin 'vim-scripts/OmniCppComplete'

Plugin 'Valloric/YouCompleteMe'

" 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

" Brief help

" :PluginList - lists configured plugins

" :PluginInstall - installs plugins; append `!` to update or just :PluginUpdate

" :PluginClean - confirms removal of unused plugins; append `!` to auto-approve removal

" see :h vundle for more details or wiki for FAQ

" Put your non-Plugin stuff after this line

syntax enable

colorscheme monokai

let g:ycm_global_ycm_extra_conf='~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/ycm/.ycm_extra_conf.py'

执行插件安装

vim +PluginInstall +qall

1	vim +PluginInstall +qall

三、增加配色方案

我这里使用monokai 配色方案：https://github.com/sickill/vim-monokai

下载对应的monokai.vim 文件放到 ~/.vim/colors/ 即可

mkdir ~/.vim/colors
wget -O ~/.vim/colors/monokai.vim https://raw.githubusercontent.com/sickill/vim-monokai/master/colors/monokai.vim

1 2	mkdir ~/.vim/colors wget -O ~/.vim/colors/monokai.vim https://raw.githubusercontent.com/sickill/vim-monokai/master/colors/monokai.vim

四、安装Clang

（此步骤可选，因为安装这个是为了C语言家族语法补全功能）

sudo yum install cmake -y
cd ~/.vim/plugin/YouCompleteMe  
./install.py --clang-completer

sudo yum install cmake -y

cd ~/.vim/plugin/YouCompleteMe

./install.py --clang-completer

五、测试

打开个cpp文件，测试下是否还会报错吧~~

vim demo.cpp

1	vim demo.cpp
