Moving from vim split to tmux pane: protocol version mismatch (client 7, server 8)

[lucasdellabella]

I can't move from vim out to a Tmux pane. Unlike most of the issues I've found online where the server version is lower than the client's. here the client version is lower than the server's and I'm not sure what to do.

Any help would be appreciated! Thanks :)

Can you clarify how you are figuring out that the client and sever version differ? Are you getting a specific error message? I haven’t run into the server mismatch much, and if I remember correctly, I think it only occurred when I upgraded tmux. Have you tried closing all tmux sessions (use `tmux list-sessions` to confirm) and then restarting? The last thing I’d check is if your tmux executable is different between a normal shell, and your shell within tmux. This would likely be due to a difference in your PATH across those two contexts. Please check into the above items, and let me know if you’re still having issues.

@christoomey I'm having the same error. I got the client / server version by running the following in a shell in a tmux pane.

 ~ ps -o state= -o comm= -t $(tmux display-message -t 1 -p '#{pane_tty}')
protocol version mismatch (client 7, server 8)
R ps
S zsh

Interesting.
There is not much that we can do here probably, but should ensure that is is reported properly.

Could you test #201 with it, since it does not use ps anymore, we might be able to report it better there.

What tmux versions (client and server) are you using?
