Does the shadow-clj project run outside of an editor, i.e from a terminal

yup from a terminal

I get same error with cljs-jack-in also

I did see some kind of parseclj error when I updated the Cider package yesterday. I simply restarted Emacs and the problem did not occur again

I can use cljs-jack-in with a figwheel-project without any problems

yup I upgraded spacemacs and then it broke, It was working couple of hrs back 🙂

then I reinstalled both spacemacs and your config, but still getting the error

I was having the same issue and did a package rollback to yesterday and now it works again 🤷

still on latest develop commit so its not that

I’m guessing its a bug in the newest cider release? but I don’t update packages often so could be anything

There was a new dev release of cider today, 30th September. Perhaps the dev release before that should be installed

sorry will need some help here, I am relying on spacemacs layers to install the packages, how do I go back to prior cider package ?

in the spacemacs buffer there is a button called ‘rollback packages’, if you click that you can return to an earlier state

or you can do it manually in your .emacs.d

Thanks everyone for the help, deleting cider, parseedn, parseclj and then installing again did the trick
