I can't run Dirac on MacOS, it keeps complaining about org.clojure/data.json - even though it is listed as a dependency

Hi,

I am trying to install Dirac on a Macbook Air M1 running Monterey 12.5.

I am following the documentation which indicates:

curl -s https://raw.githubusercontent.com/binaryage/dirac/master/install > /tmp/dirac.install && sudo bash /tmp/dirac.install

The installation seems to have worked out since it exists on binaries:

   Pedros-MacBook-Air:bin pedro$ pwd
   /usr/local/bin

   Pedros-MacBook-Air:bin pedro$ ls -1
   dirac
   lein

Unfortunately, when I go to the 2nd step on manual which is running dirac, the error below is retrieved:

   Pedros-MacBook-Air:bin pedro$ dirac

Initially, I tried running it at home folder. I thought it would work out fine.

Then, I decided to run it inside a project folder that had the file clojure/data/json.clj included in the the project.clj file. Unfortunately, even this approach did not work out.

Below you see a simplified version of the project.clj file:

(defproject abcd    ; Should be copied from shadow-cljs.edn
  :description "xxxx"
  :url "xxxx"

  :dependencies [[org.clojure/clojure "1.9.0"]
                 [org.clojure/clojurescript "1.10.339"]
                 [org.clojure/tools.nrepl "RELEASE"]
                 [binaryage/devtools ~devtools-version]
                 [binaryage/dirac ~dirac-version]
                 [org.clojure/data.json "2.4.0"]
                 [figwheel ~figwheel-version]
                 ;; Selmer for templating of .json config files
                 [selmer "1.12.50"]]

... (omitted content because it seems irrelevant) ...

  :profiles {:repl
             {:repl-options {:port             8230
                             :nrepl-middleware [dirac.nrepl/middleware]
                             :init             (do
                                                 (require 'dirac.agent)
                                                 (dirac.agent/boot!))


}}})

1 - I thought Dirac would work out even outside of the project folder. Is it necessary to be in the project folder?

2 - Why is Dirac complaining about the Json library even though it is listed as a dependency? Is there any difference between clojure/data/json.clj (error message retrieved) and org.clojure/data.json (my dependency)?

Thanks!

There should be a better way of doing this but below worked for me:

Add this dependency to your ~/.clojure/deps.edn (create it if it doesn't exist)

{:deps {org.clojure/data.json {:mvn/version "2.4.0"}}}

Should load okay, I noticed that it also needs Google Chrome Canary installed

Thank you for trying to help!

{:deps {org.clojure/data.json {:mvn/version "2.4.0"}}}

There is something weird here. When I opened the file .clojure/deps.end, there was "code content" inside the file. But, everything was comment-out:

;; The deps.edn file describes the information needed to build a classpath.
;;
;; When using the `clojure` or `clj` script, there are several deps.edn files
;; that are combined:
;; - install-level
;; - user level (this file)
;; - project level (current directory when invoked)
;;
;; For all attributes other than :paths, these config files are merged left to right.
;; Only the last :paths is kept and others are dropped.

{
  ;; Paths
  ;;   Directories in the current project to include in the classpath

  ;; :paths ["src"]

  ;; External dependencies
 
  ;; :deps {
  ;;   org.clojure/clojure {:mvn/version "1.11.1"}
  ;; }

  ;; Aliases
	;;   resolve-deps aliases (-R) affect dependency resolution, options:
	;;     :extra-deps - specifies extra deps to add to :deps
	;;     :override-deps - specifies a coordinate to use instead of that in :deps
	;;     :default-deps - specifies a coordinate to use for a lib if one isn't found
	;;   make-classpath aliases (-C) affect the classpath generation, options:
	;;     :extra-paths - vector of additional paths to add to the classpath
	;;     :classpath-overrides - map of lib to path that overrides the result of resolving deps

  ;; :aliases {
  ;;   :deps {:extra-deps {org.clojure/tools.deps.alpha {:mvn/version "0.14.1212"}}}
  ;;   :test {:extra-paths ["test"]}
  ;; }

  ;; Provider attributes

  ;; :mvn/repos {
  ;;   "central" {:url "https://repo1.maven.org/maven2/"}
  ;;   "clojars" {:url "https://repo.clojars.org/"}
  ;; }
}

Is this expected?
