I'm currently attempting to work through "Clojure for the Brave and True" (in particular, trying to set it up) and I'm running into some trouble. I'm on Windows 10 so I installed Leiningen according to the instructions on the website, but the lein commands only work on the Desktop where I installed it, not in the actual project folder which is located on the desktop (navigating to the actual folder does not let me run it; using lein run
on the Desktop simply results in the error "No :main namespace specified in project.clj."
Have I done something wrong in installing leiningen?
