Need to see your zsh configuration.

[pierot]

I use oh-my-zsh.
This is my .zshrc: https://github.com/pierot/termieter/blob/master/symlinks/zshrc

[mafredri]

How have you installed pure, npm? If so, have you also followed the instructions for oh-my-zsh integration in the README? The two methods might conflict with each other.

For example, if you have copied/symlinked ~/.oh-my-zsh/custom/async.zsh you should remove it (assuming npm installation).

[pierot]

I didn't install it through npm. Just manually copying and symlinking the files.

[mafredri]

Where did you symlink them?

Ok, that kind of looks fine but not sure what oh-my-zsh does in the background. So let's start with the basics. Can you get zpty working at all? Try the following commands:

zmodload zsh/zpty
zpty cat cat
zpty -L  # list zpty instances
zpty -w cat hello world
zpty -rt cat

The final command should print hello world.

[pierot]

➜  tmp  zmodload zsh/zpty
➜  tmp  zpty cat cat
➜  tmp  zpty -L
^Czpty cat cat
➜  tmp  zpty -w cat hello world
➜  tmp  zpty -rt cat
➜  tmp

You can see I had to CTRL+C the zpty -L command as it kept blank for over an hour.
Also, there is no hello world ...

[mafredri]

Do you experience the same behavior even if you completely disable your zsh modifications? E.g. rename your .zshrc so that it isn't sourced.

[pierot]

Strangely enough, all seems well no. I cancelled pure for a couple of days.
Yesterday I tried to re-enable it and see and now everything works as before ..

[mafredri]

Maybe you've rebooted your computer in between? Anyhow, that's great. Love it when things sort themselves out 🎉 !

[raffylopez]

You might have hit the resource limit for processes/open files. This happened to me when I had so many zsh and tmux processes open, up to the point that tmux won't even allow me to create additional panes, and pure would unexplainably give me the same async_job:zpty:2: no such pty command: prompt_pure error at the same time. Check (https://github.com/ChrisJohnsen/tmux-MacOSX-pasteboard/issues/30)

You can try to forcibly close down your processes (albeit ungracefully):
sudo \ps -ef | awk '{print $1}' | tail -n +2 | awk '{system("pkill -u " $1)}', then check perhaps if the problem still persists.

I had the same error this morning. It disappeared when I closed my 20+ tmux sessions 🤷‍♂️

[cjayross]

I'm having this same issue, yet it happens when I am only using a single terminal session. Particularly, it happens when I am working within a git repo.
