打开命令终端　输入vi

若系统已安装 Vim,则会出现以下界面

若未安装

请尝试使用命令 apt-get 或安装

此时输入安装命令：sudo apt-get install vim

等待安装即可

安装完成后，在终端输入　vim --version 查看是否安装成功。

PS：有的人会出现输入安装命令后，等待很久都无法安装的情况

这可能是因为安装源的问题

解决方法：更换安装源

１.在终端输入

sudo gedit /etc/apt/sources.list  

该命令的作用是用gedit打开安装来源文件　sources.list

２.替换安装源，使用阿里的云

将文件中的内容替换为以下内容

# deb cdrom:[Ubuntu 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.1)]/ xenial main restricted

deb-src http://archive.ubuntu.com/ubuntu xenial main restricted #Added by software-properties
