Installer not working under wezterm about nix-installer

Ah ha, this happened to me using Alacritty.
Sadly, copying over the terminfo for Alacritty and importing that didn't solve it, but setting export TERM=xterm-color did.

Also tried using @cole-h's #869 and that appeared to work (at this point, Nix was already installed, so it told me to use sudo -i nix upgrade-nix instead, but it didn't crash complaining about not being able to get a terminal!).

It sounds like you don't have wezterm's terminfo loaded. That message is coming from here:

nix-installer/src/cli/interaction.rs

Lines 23 to 24 in 06eaf88

	let mut term =
	term::terminfo::TerminfoTerminal::new(stdout).ok_or(eyre!("Couldn't get terminal"))?;

Could you try out #869 and see if that works for you? You should be able to try it out with:

curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix/pr/869 | sh -s -- install

I do have wezterm terminfo loaded but don't know why it's not being detected. I was using tmux previously but it didn't work even outside of tmux.
Using the fallback patch fixes the problem
