Vim折腾笔记(六) | CentOS7中配置Python环境的Vim8

说明

• VM15虚拟机中的CentOS7
• Xshell连接

安装最新版vim

• 增加最新版vim源
  curl -L https://copr.fedorainfracloud.org/coprs/lantw44/vim-latest/repo/epel-7/lantw44-vim-latest-epel-7.repo -o /etc/yum.repos.d/vim-latest.repo
• 更新vim
  yum update -y
• 验证vim
  vim

• 在vim中输入命令 :echo $VIMRUNTIME 来查看Vim的运行目录

配置最新版vim

• 创建用户的.vim文件夹
  mkdir ~/.vim
• 创建用户的.vimrc文件
  touch ~/.vimrc
• 创建vim的主题文件夹
  mkdir -p ~/.vim/colors

配色方案

• 安装gruvbox配色方案
  curl -fLo ~/.vim/colors/gruvbox.vim --create-dirs https://raw.githubusercontent.com/morhetz/gruvbox/master/colors/gruvbox.vim
• 配置用户的vim
  vim ~/.vimrc

" gruvbox配色方案
colorscheme gruvbox

插件管理

• 安装开发工具
  yum grouplist
yum groupinstall "开发工具" -y 或 yum groupinstall Development tools -y
• 安装部分依赖
  yum install cmake python-devel clang kernel-devel ncurses-devel yum-utils epel-release https://centos7.iuscommunity.org/ius-release.rpm -y
• 安装python3和pip3

yum search python3 | grep devel

yum install python36u python36u-devel python36u-pip -y

• 创建python3连接符
  ln -s /usr/bin/python3.6 /usr/bin/python3
• 创建pip3链接符
  ln -s /usr/bin/pip3.6 /usr/bin/pip3
• 配置pip3
  mkdir ~/.pip && cd ~/.pip
vim pip.conf

[global]
index-url = http://pypi.douban.com/simple
[install]
trusted-host = pypi.douban.com

• 版本查看
  python -V
python3 -V
pip3 -V
• 升级pip3
  pip3 install --upgrade pip

• 安装vim_runtime配置方案
  git clone --depth=1 https://github.com/amix/vimrc.git ~/.vim_runtime
sh ~/.vim_runtime/install_awesome_vimrc.sh
• 下载plug.vim(vim插件管理器)
  curl -fLo ~/.vim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
• 配置用户的vim
  vim ~/.vimrc

" F11快捷键激活/取消paste模式
set pastetoggle=<F11>

• 配置用户的vim

  vim ~/.vimrc
