I am fairly new to ruby and trying to write a gem file but the following error occurs.I have updated bundler and the relevant gems as was suggested in other posts.
Developing with
ubuntu 18.04LTS
ruby 2.5.1p57
gem 3.1.2
Traceback (most recent call last):

These are my code what I am tring to execute
command_option.rb
module Vcdm
class CommandOption
attr_reader :name, :type, :description
def initialize(name, type, description)
#name = name
#type = type
#description = description
end
end
end
hostfile.rb
require 'vcdm/command_interface'
module Vcdm
class HostfileCommand
as = CommandOption.new("--path STRING", String, "custom hosts path")
IS_PUBLIC_COMMAND = true
SYNTAX = 'vcdm hostfile'
SUMMARY = 'adds the ingress url to the users hostfile'
DESCRIPTION = ""
EXAMPLE = "vcdm hostfile --path=/mnt/c/Windows/System32/drivers/etc/hosts"
EXAMPLE_DESCRIPTION = ""
implements CommandInterface
end
end
command_interface.rb
require 'class_interface'
class CommandInterface
IS_PUBLIC_COMMAND = true | false
SYNTAX = String
SUMMARY = String
DESCRIPTION = String
EXAMPLE = String
EXAMPLE_DESCRIPTION = String
OPTIONS = Array
def initialize
end
def execute(args, options)
end
end
Is there anything wrong?

Answer 1

It feels to me like you are missing a
require 'vcdm/command_option'
in your hostfile.rb. Just add that line to the top of that file.

Answer 2

try putting this in 'config/application.rb'
config.eager_load_paths << "#{Rails.root}/lib"
and then in 'hostfile.rb'
require 'vcdm/command_interface'
module Vcdm
include CommandOption
class HostfileCommand
...
