When trying to close a terminal in jupyter, I get the following error. Any suggestions?

I just checked. This also happens if I just type exit.

Thanks. It matters because closing the tab is a very different operation from exiting the terminal, and I wasn't sure which you were doing.

I can't reproduce this at the moment. Are your 'notebook' and 'terminado' packages both up to date?

Yup, those look like the latest ones. Not sure what's going on, then.

So here’s a bit more about this.

My jupyter notebook server is running on a secondary account (jup) on my MacOS machine. If I am logged into my primary account (gideon) on that machine open up the jupyter server that’s running on jup and open/close a terminal, it’s fine. If I am away from that machine, and log in remotely in a web browser, that’s when I have the issue of terminals not closing.

More weird stuff. If I open a terminal and immediately close it (with Ctrl-D), it's fine. If I do anything, even

ls

then when I hit Ctrl-D, I generate that error.

And now the problem has disappeared. I recently upgraded to the new High Sierra. Perhaps it was related to that?
