Getting an unsuitable terminal error when opening tmux after switching to homebrew

homebrewtmux

Longtime macports user (tmux / 256color etc worked fine). Recently decided to switch over to homebrew. Have most things working again.

tmux throws the following error when launching (have not changed terminal or .tmux.conf)

open terminal failed: missing or unsuitable terminal: xterm-256color

I commented out the terminal settings in my tmux.conf and tried setting my $TERM to xterm. The same thing happens (replacing xterm-256color with whatever I have $TERM set to). My gut says that I was using a terminfo from macports and that I'm using the system terminfo with homebrew. Not sure how to do this with homebrew to test.

Possibly relevant versions numbers of stuff:

  • homebrew 0.9.5
  • tmux 1.9a
  • iterm 2.0.0.20150412
  • yosemite (up to date)
  • zsh 5.0.5

Best Answer

I had to add:

set-option -g default-terminal screen-256color

to my ~/.tmux.conf to get it to work under all the same versions you reference above on Yosemite. You can see my tmux configuration file here if you'd like a point of reference.
