7 years ago The classpath is different when you use lein figwheel and lein repl. The figwheel plugin adds the all the ClojureScript paths ["src/cljs" "src/cljc" "env/dev/cljs"] to the classpath. And in order for the compiler to find the source code it searches the classpath. In many cases things will still work without setting the classpath correctly.
You will have to add ["src/cljs" "src/cljc" "env/dev/cljs"] the top level :source-paths in your project.clj to get the behavior you want.
When I use
requirein the figwheel-sidecar REPL, I get a spurious error message.Steps to reproduce:

Note in particular that the namespace is in fact defined. Thus the error is spurious(?).

The error does not happen with

Also, if I use
cljs.core/requireinstead ofrequire, then there's no error. What??
