Uncaught TypeError: Cannot read property 'emit' of null

bobbyrauchenberg commented 7 years ago

Sorry, i raised an issue earlier (https://github.com/atom-haskell/ide-haskell/issues/197) which you said was fixed in 1.9.6, so i upgraded and now get this. Apologies if I've done something stupid along the way :)

Uh... did you restart Atom after updating? It usually wants you to...

lierdakil commented 7 years ago

I'm pretty sure this can only happen if ide-haskell goes away (disabled, removed or updated) with repl open...

bobbyrauchenberg commented 7 years ago

Yeah i restarted. I've just been using ghci through Term3 today (i.e. no repl) and have not seen the issue

lierdakil commented 7 years ago

So... you closed the issue. Did it "fix itself" or do you have other reasons?
