Hey folks sorry if this has been already asked but is anyone having this problem:

my figwheel repl is spitting out an endless stream of that stack trace

though it seems to work.

I've tried deleting all my code and most the obvious CLJS packages from my project.clj and it still is happening...

^ seems like an old clojurescript version was the culprit

Did a double take on the project.clj and saw I was on clojure 1.8 and cljs 1.9.521

@djtango clojure 1.9 is required

@kiemdoder that is very strange

reminder that #figwheel-main is the best channel for figwheel.main related discussion

@bhauman I created a Leiningen project with https://rigsomelight.com/figwheel-main-template/ in the mean time and Rebel works fine there when I start Figwheel with lein fig:build.

are you on windows?

hmmm well figwheel.main requires rebel-readline dynamicly and uses it if its there

so it sounds like something missfired

like if you start clj with that deps.edn

I followed the Figwheel tutorial

you should be able to require ’rebel-readline-cljs.main

its sounds like you did things right

let me have a look

I created a new dir, copied the deps.edn file and now it works. I can see "[Rebel readline] Type :repl/help for online help info"

maybe creating the Leiningen project with the template fixed something

@kiemdoder there is a .cpcache dir that caches the classpath maybe that got out of sync somehow

I have Rebel readline in my deps.edn but when I run "clojure -m figwheel.main" I don't see evidence of Rebel on my console.
