tmux version "next-2.9": TypeError: '<' not supported between instances of 'str' and 'int'

[kaushalmodi]

Hello,

One of the 2 upgrades (python or tmux) broke tmuxp for me:

• tmux next-2.9 (using the latest tmux built from master as of today)
• Python 3.7.0

I uninstalled and reinstalled tmuxp using:

pip3 uninstall tmuxp
pip3 install --user tmuxp

But when I try to load a tmuxp config (as I always do, and worked), by doing tmuxp load servers -d, I get:

Traceback (most recent call last):

Maybe tmuxp doesn't like the new non-int version string of tmux? tmux/tmux@bc6211c

[kaushalmodi]

I confirm this bug in tmuxp. After I reverted that specific commit in tmux, and rebuilt it, tmuxp works fine.

I also ran into this using tmux next-2.9 (the latest Homebrew release). The issue is in libtmux. I sent a PR tmux-python/libtmux#172 and verified that it works .

@kaushalmodi @sloria I'm going to tag a release this weekend. Maybe sooner.
