TMUX_AUTOSTART=true closes my terminal at first

Question

I added the tmux plugin to my .zshrc file.  When I try to make it run on startup with TMUX_AUTOSTART=true, it just shows the terminal window and disappears in under a second.  Then I open it again and I can work.  Again after a while if I close the terminal and try to run it again it might happen, or it might run correctly and let me work.  This is getting really annoying.  When I try other code to run tmux on start up, like these:

if command -v tmux &> /dev/null && [ -n "$PS1" ] &&
          [[ ! "$TERM" =~ screen ]] && [[ ! "$TERM" =~ tmux ]] &&
          [ -z "$TMUX" ]; then
    exec tmux
fi

or

[[ $- != *i* ]] && return
[[ -z "$TMUX" ]] && exec tmux

or

[ -z "$TMUX"  ] && { tmux attach || exec tmux new-session && exit;}

or any other code, the terminal just opens up and closes itself in under a second, forever.  After that, it closes every time.

Answer 1

You have to put your ZSH_TMUX_AUTOSTART between your plugins and your oh-my-zsh source.

Like this:

plugins=(tmux)

ZSH_TMUX_AUTOSTART=true

source $ZSH/oh-my-zsh.sh

Answer 2

I had the same problem and I solved it by adding:

[ -z "$TMUX"  ] && { tmux attach || exec tmux new-session && exit; }

To the very top of my .zshrc, not below anything.

Answer 3

ZSH_TMUX_AUTOCONNECT=false

worked for me
