Given the dummy rake task below

require "optparse" namespace :a do namespace :b do task c: :environment do options = {} OptionParser.new do |parser| parser.banner = "" parser.on("-v", "--verbose", "Run verbosely") do |v| options[:verbose] = v end end.parse! puts "options: #{options}" end end end 

How should I call it?

From my understanding, the way should be bin/rails a:b:c -v 3 or bin/rails a:b:c -- -v 3

But both ways generate:

Unrecognized command "3" (Rails::Command::UnrecognizedCommandError)

What am I missing here?

I'm running the task on a Mac.
