Problem starting weasel repl

jmckitrick commented 9 years ago

Here's what I'm getting running lein trampoline repl

pts.server=> (require 'weasel.repl.websocket)
nil
pts.server=> (cemerick.piggieback/cljs-repl :repl-env (weasel.repl.websocket/repl-env :ip "0.0.0.0" :port 9001))

IllegalStateException Can't change/establish root binding of: *cljs-repl-options* with set  clojure.lang.Var.set (Var.java:221)

This seems to happen only when lein trampoline repl is used, and it doesn't seem Weasel-specific. The same error occurs when using Piggieback with the Node.js REPL, for example:

user=> (require '[cljs.repl :as repl])
nil
user=> (require '[cljs.repl.node :as node])
nil
user=> (cemerick.piggieback/cljs-repl
  #_=>          :repl-env (node/repl-env)
  #_=>          :output-dir ".cljs_node_repl"
  #_=>          :cache-analysis true
  #_=>          :source-map true)

IllegalStateException Can't change/establish root binding of: *cljs-repl-options* with set  clojure.lang.Var.set (Var.java:221)

I don't think this is Weasel's issue.

See also https://github.com/cemerick/piggieback/issues/7#issuecomment-21796140 (edit: updated with more specific link). Maybe it's a configuration issue? I don't use lein trampoline so I'm afraid I can't be much help :smiley:

I have this same problem and I was wondering what's causing it. I initially thought it was from lein trampoline but I tried using lein run and I had the exact same IllegalStateException. Here's my configuration:

It may be true that this isn't Weasel's issue, as you say — so I'll post something similar on the piggieback Git repo and ask the same question.

Thanks for your help!
