Neovim+LazyVIM

Neovim, 編譯時，相依滿多東西的，麻煩

a. sudo apt install npm lua-luv-dev lua-lpeg \
   libunibilium-dev libutf8proc-dev libluajit-5.1-dev -y

b. 其它的，缺什麼補什麼
   lua, tree-sitter
   fzf, luarocks(不裝，Checkhealth裡會有WARNING)，但它不支援lua 5.5

c. 符號亂碼的話，裝Nerd Font字型：
       nerdfonts
   下載:
       JetBrainsMono Nerd Font
   安裝:
       font
   Terminal:
       要選有Nerd Font的字型，所有符號就能正常下載
       ex: JetBrainsMono Nerd Font

LazyVim

安裝:
