vim

直接安装YouCompleteMe

sudo apt install vim-youcompleteme

nvim

使用nvim-lspconfig配合nvim-cmp

配置参考

https://github.com/hrsh7th/nvim-cmp​​​​​​

有网络使用lazy.nvim

没有网络github下载直接解压到插件目录 ~/.config/nvim/pack/nvim/start/

catppuccin  cmp-buffer  cmp-cmdline  cmp-nvim-lsp  cmp-path  nvim-cmp  nvim-lspconfig  nvim-tree  nvim-web-devicons  plenary.nvim  telescope.nvim  which-key.nvim
