lighttable does not work after upgrading to Clojure 1.7.0 ?

[Ghassan Ayesh]

We couldn't connect.

Looks like there was an issue trying to connect to the project. Here's what we got:

any idea what's going on? Thanks.

Something in your project dependencies is pulling in a version of the dependency "fs" that is not compatible with the one LightTable uses.

Similar to say this issue: https://github.com/bhauman/lein-figwheel/issues/119


Extending this pull request: https://github.com/LightTable/Clojure/pull/48 to also inline fs (and release a new lein-light nrepl middleware) could probably prevent future dep clashes like this one.

Cheers
