Unfortunately, I am not able to make the nvim-tree plugin working for me. I installed the nvim-web-devicons as recommended, google a lot but can't find a solution. Please find a screenshot and my init.lua attached. Any help is appreciated.

enter image description here

I believe you have to:

  • Install a Nerd Font in your system
  • If you are using a terminal application (e.g. Tilix) you may have to install the font in that application too
  • Configure Vim to use the font by changing the guifont option
3
  • Oh, that did the trick! I, however, had to set the font in the terminal application as I use nvim in Tilix.
