VIM插件YouCompleteMe安装以及vim常用插件

YouCompleteMe

YouCompleteMe，简称YCM，是一个模糊代码搜索，自动补全的VIM插件

安装

第一步： 安装VIM8.0

1.查看vim版本信息

[root@localhost ~]# vim --version | head -1
VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Oct 30 2018 19:56:57)

需要使用vim8.0才能安装自动补全插件YouCompleteMe，如果版本已经是8.0则不需要以下步骤

2.卸载旧版VIM

[root@localhost ~]# yum remove vim -y

3.安装git从github拉取最新版vim

[root@localhost ~]# yum install git -y
[root@localhost ~]# git clone https://github.com/vim/vim.git

4.安装VIM8.0相关依赖，并编译VIM

[root@localhost ~]# yum install python python-devel ncurses ncurses-devel -y
[root@localhost ~]# cd vim-master
[root@localhost ~]# ./configure --with-features=huge --enable-pythoninterp --with-python-config-dir=/usr/bin/python2.7-config  --enable-cscope --enable-multibyte --prefix=/usr/local/vim
[root@localhost ~]# make && main install 

5.复制相关文件到/usr/bin/目录下

[root@localhost ~]# cp  /usr/local/vim/bin/* /usr/bin/

6.查看VIM版本信息

[root@localhost YouCompleteMe]# vim --version | head -1
VIM - Vi IMproved 8.1 (2018 May 18, compiled Apr  6 2019 11:53:14)

第二步：安装Vundle

1.下载VIM插件管理器Vundle

[root@localhost ~]# git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim

2.编写配置文件.vimrc

在call vundle#begin()和call vundle#end()指令之间编写需要安装的插件，编写完之后退出

" 关闭兼容模式
set nocompatible              " required
" 关闭文件类型检测
filetype off                  " required

" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()

" Vundle vim插件管理器
Plugin 'gmarik/Vundle.vim'

" YouCompleteMe 自动补全神器 
Bundle 'Valloric/YouCompleteMe'

let g:ycm_global_ycm_extra_conf='~/.ycm_extra_conf.py'
let g:ycm_server_python_interpreter='/usr/bin/python3.6'
let g:ycm_collect_identifiers_from_tag_files = 1
let g:ycm_seed_identifiers_with_syntax = 1
let g:ycm_confirm_extra_conf=0
let g:ycm_key_invoke_completion = ''
nnoremap  :YcmForceCompileAndDiagnostics

call vundle#end()            " required
filetype plugin indent on    " required

3.安装插件

[root@localhost ~]# cd /root/
[root@localhost ~]# vim .vimrc 
# 进入之后，输入命令
:PluginInstall
# 然后安静等待一段很长的时间

报错：

The ycmd server SHUT DOWN (restart with ':YcmRestar...ng it. Follow the instructions in the documentation.

解决方式：

[root@localhost ~]# yum install build-essential cmake clang  libclang  gcc-devel gcc-c++ -y
[root@localhost ~]# cd .vim/bundle/YouCompleteMe/
[root@localhost ~]# python3 install.py

4.编写~/.ycm_extra_conf.py配置文件
