Ubuntu Server 20.04 LTS 环境下搭建vim 编辑器Python IDE的详细步骤

安装配置vim-plug

安装vim-plug

curl -fLo ~/.vim/autoload/plug.vim --create-dirs \
   https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

配置vim-plug

在家目录下创建.vimrc配置文件

在.vimrc下填写配置

vim ~/.vimrc

call plug#begin()
Plug 'neoclide/coc.nvim'
Plug 'asins/vimcdoc'
Plug 'preservim/nerdtree'
Plug 'mhinz/vim-startify'
Plug 'luochen1990/rainbow'

call plug#end()

安装coc.nvim插件

更新vim

sudo add-apt-repository ppa:jonathonf/vim

sudo apt-get update

sudo apt-get install vim

安装node

sudo apt update
sudo apt install nodejs npm
sudo curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt install nodejs

添加coc.nvim到.vimrc文件

call plug#bing()
Plug 'neoclide/coc.nvim', {'branch': 'release'}  
call plug#end()

:PlugInstall 安装自动补全插件
:CocInfo 检查插件安装情况
:CocInstall coc-json coc-tsserver支持JSON和Typescript相关子插件

配置服务器

:CocConfig添加Python配置数据
:CocInstall coc-pyright
