• 公司自建源

pip加速

• pip configuration

• cd && mkdir .pip && cd .pip && touch pip.conf

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

配置neovim

• ubuntu18.04这样安装默认是0.6.1版本
  • sudo apt-add-repository ppa:neovim-ppa/stable
  • sudo apt-get update
  • sudo apt-get install neovim
• 可以源码编译0.8.2

plugins

• 参考init.vim, 放在~/.config/nvim/下

字体

插件

• coc需要安装nodejs, >= 12.12, copilot需要 >= 16.x

    • sudo apt-get install curl
  • 安装nodejs
    • curl -sL https://deb.nodesource.com/setup_16.x | sudo -E bash -
    • sudo apt-get install -y nodejs
  • 更新coc版本
  • yarn install
  • auto-save需要coc
• CocInstall coc-marketplace
  • 可以直接在vim里面进行插件管理
  • CocList marketplace python就是搜索python相关的插件
• coc中的自动补全会和tab(缩进)冲突
