getting required namespace not available error on Reagent Clojurescript project

Question

I'm trying to break out some of the page components from core.cljs from https://github.com/reagent-project/reagent-frontend-template , but am getting this error: The required namespace "reagent-project.utils.path-for" is not available, it was required by "reagent_project/pages/home.cljs".

my files are as follows:

path-for.cljs

(ns reagent-project.utils.path-for
  (:require
   [reitit.frontend :as reitit]))

(defn path-for [route & [params]]
  (if params
    (:path (reitit/match-by-name router route params))
    (:path (reitit/match-by-name router route))))

home.cljs

(ns reagent-project.pages.home
  (:require
   [reagent-project.utils.path-for :refer [path-for]]
   [reagent.core :as reagent :refer [atom]]))

(defn home-page []
  (fn []
    [:span.main
     [:h1 "Welcome to reagent-project"]
     [:ul
      [:li [:a {:href (path-for :items)} "Items of reagent-project"]]
      [:li [:a {:href "/broken/link"} "Broken link"]]]]))

Answer 1

Do you have the correct filename and is it on the classpath?

Assuming you have :source-paths ["src"] then the expected filename would be src/reagent_project/utils/path_for.cljs? Note that - is required to be turned into a _ for .clj(s) source files.
