If you were to run clojure directly yourself you get more info:

Perhaps this involves an upstream enhancement in tools.deps.alpha, or alternatively, lein-tools-deps can run clojure -Sdescribe itself and show :err?

I was getting the same vague error message: "Unable to locate Clojure's edn files". I ran clojure and the error message told me immediately what I needed to know to fix the problem.

running into this issue a year later, did some developing on mac and now switched to ubuntu where there's no clj client out of the box apparently, running clojure gets me into user ns with no problem, still don't know what's missing but it appears to be related dependencies ?! :

can't run lein deps even, get the same error.

apparently clj is not in apt-get repos and it's not sufficient to just have clojure cli on ubuntu.
okay, so basically I had to install the clj client (props to this article) and that got me clj which was needed to clone the github repos I was using in my deps.edn
thanks for the lein-tools-deps by the way, big fan !
now I can run my aliases in peace : clj -A:build-dev (I use figwheel's default)
