Clojurians Log v2

Having issues figuring out what’s wrong with my setup that’s causing the following error when I try to set up my repl development for a repo.

user=> (require 'port.main)
Syntax error (FileNotFoundException) compiling at (user.clj:1:1).
Could not locate m/api__init.class, m/api.clj or m/api.cljc on classpath.

What's in user.clj?

What's m.api? Almost looks like m is expected to be an alias but the alias wasn't defined in a require or something
