Background: I am trying to make a fresh start with a CLJS project that started with lein mies and then, after a half-baked attempt to switch to figwheel broke on the build, and now I am trying to get that project going again, while at the same time exploring the CLJS build field. Constraint: I do not want to involve React directly or indirectly thru Reagent et al. My plan is to get a minimalist hello world going and then grow back the original project just by copying in the original source. Working from the figwheel template page https://rigsomelight.com/figwheel-main-template/ I managed to get a lein-based minimal project running. yay. Then I tried the deps variant:

$ clj
Clojure 1.11.1
user=> ^C
$ clojure -Ttools install io.github.seancorfield/deps-new '{:git/tag "v0.4.13"}' :as new
Installed new
$ clojure -Ttools install com.github.seancorfield/clj-new '{:git/tag "v1.2.399"}' :as clj-new
Installed clj-new
$ clj -X:new clj-new/create :template figwheel-main :name yourname/hello-world :args '["--reagent"]'
Namespace could not be loaded: clj-new
