jsloader GET pprint.js 404, cannot see return in cljs-repl

keep getting this error message in the browser whenever connected to cljs-repl, and after every command from cljs-repl (and I can't see the return value of each command)

here's the error in the browser:

jsloader.js:216 GET http://localhost:3000/js/app.out/cljs/pprint.js net::ERR_ABORTED 404 (Not Found)

and here's the error message in the cljs-repl:

cljs.user=> (js/alert "test")
