Have you gone through these steps? I usually type tmux attach after typing tmux. Is it possible you have no session to attach to? I would be surprised in hyper has any role to play here.

Thanks for the link, none of what is listed help, I think it is similar to alacritty/alacritty#1687 but I don't see it is solved there as well

I do have tmux sessions as listed with tmux ls but tmux a fail with open terminal failed: not a terminal

[voronoipotato]

if you open git bash does it work?

[mulyoved]

Yes, git and other bash command work fine, the problem with tmux only
tmux work fine on ConEmu

[kentac55]

Same problem occured on Hyper 3.0.2 with msys2's tmux 2.9(without any config) and $TERM=xterm|xterm-256color
ssh, vim, and other commands work fine

    shell: 'C:\\Users\\kentac55\\scoop\\apps\\msys2\\20180531\\usr\\bin\\bash.exe',
    shellArgs: ['--login', '-i'],
    env: {
      'HOME': 'C:\\Users\\kentac55',
      'MSYS2_PATH_TYPE': 'inherit',
      'LANG': 'en_US.UTF-8'
    },

@kentac55 Don't supposed you managed to sort this? Exactly same environment here, "not a terminal message" only in Hyper.
