Ruby Uninitialized constant error

I am using a dashing weather widget but it seems to be creating an error when I run the Ruby job file. The following is the Ruby file

require 'net/https'
require 'json'

# Forecast API Key from https://developer.forecast.io
forecast_api_key = ""

# Latitude, Longitude for location
forecast_location_lat = "45.429522"
forecast_location_long = "-75.689613"

# Unit Format
# "us" - U.S. Imperial
# "si" - International System of Units
# "uk" - SI w. windSpeed in mph
forecast_units = "si"

SCHEDULER.every '5m', :first_in => 0 do |job|
  http = Net::HTTP.new("api.forecast.io", 443)
  http.use_ssl = true
  http.verify_mode = OpenSSL::SSL::VERIFY_PEER
  response = http.request(Net::HTTP::Get.new("/forecast/#{forecast_api_key}/#{forecast_location_lat},#{forecast_location_long}?units=#{forecast_units}"))
  forecast = JSON.parse(response.body)  
  forecast_current_temp = forecast["currently"]["temperature"].round
  forecast_current_icon = forecast["currently"]["icon"]
  forecast_current_desc = forecast["currently"]["summary"]
  if forecast["minutely"]  # sometimes this is missing from the response.  I don't know why
    forecast_next_desc  = forecast["minutely"]["summary"]
    forecast_next_icon  = forecast["minutely"]["icon"]
  else
    puts "Did not get minutely forecast data again"
    forecast_next_desc  = "No data"
    forecast_next_icon  = ""
  end
  forecast_later_desc   = forecast["hourly"]["summary"]
  forecast_later_icon   = forecast["hourly"]["icon"]
  send_event('forecast', { current_temp: "#{forecast_current_temp}&deg;", current_icon: "#{forecast_current_icon}", current_desc: "#{forecast_current_desc}", next_icon: "#{forecast_next_icon}", next_desc: "#{forecast_next_desc}", later_icon: "#{forecast_later_icon}", later_desc: "#{forecast_later_desc}"})
end

and it gives the error /forecast.rb:3: invalid multibyte char (US-ASCII) (SyntaxError)

which is weird because line 3 is blank in the file.

So I decided to add # encoding: utf-8 at the beginning of the file to try to fix this but then I get the error uninitialized constant on line 4 (again a blank line). can someone help me out with this?

The complete error message was

/usr/lib/ruby/vendor_ruby/rubygems/defaults/operating_system.rb:3: warning: method redefined; discarding old default_dir
/usr/lib/ruby/1.9.1/rubygems/defaults.rb:25: warning: previous definition of default_dir was here
/usr/lib/ruby/vendor_ruby/rubygems/defaults/operating_system.rb:7: warning: method redefined; discarding old default_bindir
/usr/lib/ruby/1.9.1/rubygems/defaults.rb:96: warning: previous definition of default_bindir was here
/home/pi/xxxxx/jobs/forecast.rb:3: invalid multibyte char (US-ASCII)

Solution

I changed SCHEDULER to Dashing.scheduler and was able to get past this error.
