1. 安装Vim插件支持

  1. $ mkdir ~/.config/nvim
  2. $ touch ~/.config/nvim/init.vim

打开一个 nvim 窗口，输入 :PlugInstall。安装完成后，输入 :checkhealth。

3. 安装Coc插件

除此之外，我们还需要安装 Coc 相关插件，打开一个 Nvim 窗口，执行下面代码：

  1. :CocInstall coc-clangd coc-cmake coc-emmet coc-git coc-highlight coc-pairs
  2. :CocInstall coc-jedi coc-json coc-sh coc-snippets coc-vimlsp coc-yaml coc-syntax

参考文档：https://www.cnblogs.com/cniwoq/p/13272746.html
报错：https://www.cnblogs.com/sober-orange/p/cocnvim-build-indexjs.html

4. 常见报错

🔎报错：Unknown function: SemshiBufWipeout
解决办法：执行 :UpdateRemotePlugins，可以看见具体报错。

🔎报错：No module named pynvim
解决办法：原因在于当前 Python 环境下没有安装 pynvim 库。
