Basically do
M-x nerd-icons-install-fontsM-x all-the-icons-install-fontsDoom switched to Nerd icons recently, it’s
nerd-icons-install-fontsnow.
Hello! I was actually stuck on this for a while but turns out what worked for me wasn’t all-the-icons (frustratingly), it was nerd font icons! So run nerd-icons-install-fonts :)
/r/doomemacs
Run “Doom doctor” in the terminal, it wil tell you how to fix this error and also if you miss some other packages.
Doom doctor doesn’t tell to install the icons. There are even times that Emacs is blank and one has to install a specific font like emoji and install nerd and all the icons using Emacs in the terminal
Sure fire way: Go vanilla!
“Hey, can I get some help using this thing?”
“Yeah sure. Simple. Don’t use that thing.”
‘nerd-icons-install-fonts’ ?
thank you!
