I've had a few problems with this topic too. And here are the tricks that help me:
- Clean leain deps:
rm -rf ~/.m2/*
- download lein deps:
lein deps
in your project root - I saw this message:
"broken pipe"
when there was too much time from the last brepl interaction. So, refresh the browser and that's all - sometimes my brepl hung on the first time i was trying to evaluate the code, again try to refresh the browser
- don't forget to run:
lein cljsbuild once
before start the brepl
Good luck
PS: Anyway if you want to have a comfortable brepl experience you have to take a look to https://github.com/cemerick/austin . I have tested this brepl and works fine https://github.com/juanantonioruz/client
