Vim中C/C++开发全套配置安装，自动补全，YouCompleteMe配置，编译运行，彩色括号，文件树等）_C/C++

vim c/c++开发配置

1.基础准备

安装g++ gcc git cmake

sudo apt-get install g++ gcc cmake git

安装vim

sudo apt-get install vim

2.安装vim插件管理工具vundle

vundle让你可以非常轻松地安装、更新、搜索和清理插件

按ctrl + alt + t打开 terminal
进入到~/.vim文件夹中，如果没有则创建
```
~$ cd ~/.vim/
#如果无文件夹
#mkdir .vim
```
在~/.vim目录下创建一个bundle目录,下载vundle.vim到~/.vim/bundle目录下
```
~/.vim$ mkdir bundle
~/.vim$ git clone https://github.com/gmarik/vundle.vim.git ~/.vim/bundle/vundle.vim
```
如果无法下载，可以直接点击链接下载到该文件夹中。

3.配置~/.vimrc

在~下创建文件.vimrc

~/$ vim .vimrc

将以下内容复制到 .vimrc中

filetype off
syntax on
set rtp+=~/.vim/bundle/vundle.vim
call vundle#begin()
plugin 'vundlevim/vundle.vim'
plugin 'scrooloose/nerdtree'               " 文件树

4.安装插件

terminal中输入vim命令
```
~$ vim
```
进入到vim中后输入 :plugininstall命令安装插件

安装完成，如下如图所示
5.自动补全插件youcompleteme的配置
进行到这一步，vim基本已经配置差不多啦，最后来进行自动补全的配置。
此时打开vim底部会出现ycm的报错，现在来解决。
1. 安装python3、python3-dev
```
~$ sudo apt install python3 python3-dev
```
1. 执行如下命令(使用绝对路径)
```
~$ /usr/bin/python3 ~/.vim/bundle/youcompleteme/install.py --all --verbose
```
