Google Calendar API insert method not working on Ruby - ruby-on-rails

Question

I am trying to use Google Calendar API in my Ruby project and I meet a problem when I try to use the insert in the API. When I try the sample code on the https://developers.google.com/calendar/v3/reference/events/insert#examples,
I end up getting an error.
insertEvent.rb:2:in `<main>': uninitialized constant Google (NameError)
And if I paste this sample code after the quickstart.rb on this page
https://developers.google.com/calendar/quickstart/ruby, I will get this error:
quickstart.rb:84:in `<main>': undefined local variable or method `client' for main:Object (NameError)
Google did not get me the definition of client variable here so I do not what to insert here. I am a new learner of Ruby and thank you so much for helping.
Here is the code that I am stuck in
result = client.insert_event('primary', event)
puts "Event created: #{result.html_link}"

Ya, client isn't defined. Try this example code instead
https://github.com/googleapis/google-api-ruby-client/blob/master/samples/cli/lib/samples/calendar.rb
and
https://developers.google.com/calendar/quickstart/ruby
Important parts here:
require 'google/apis/calendar_v3'
require 'googleauth'
require 'googleauth/stores/file_token_store'
require 'fileutils'
OOB_URI = 'urn:ietf:wg:oauth:2.0:oob'.freeze
APPLICATION_NAME = 'Google Calendar API Ruby Quickstart'.freeze
CREDENTIALS_PATH = 'credentials.json'.freeze
TOKEN_PATH = 'token.yaml'.freeze
SCOPE = Google::Apis::CalendarV3::AUTH_CALENDAR_READONLY
def authorize
client_id = Google::Auth::ClientId.from_file(CREDENTIALS_PATH)
token_store = Google::Auth::Stores::FileTokenStore.new(file: TOKEN_PATH)
authorizer = Google::Auth::UserAuthorizer.new(client_id, SCOPE, token_store)
# figure out your user_id
user_id = 'default'
credentials = authorizer.get_credentials(user_id)
if credentials.nil?
url = authorizer.get_authorization_url(base_url: OOB_URI)
puts 'Open the following URL in the browser and enter the ' \
"resulting code after authorization:\n" + url
code = gets
credentials = authorizer.get_and_store_credentials_from_code(
user_id: user_id, code: code, base_url: OOB_URI
)
end
credentials
end
calendar = Google::Apis::CalendarV3::CalendarService.new
calendar.client_options.application_name = APPLICATION_NAME
calendar.authorization = authorize
event = {
summary: 'Events',
attendees: [
{email: 'lpage#example.com'},
{email: 'sbrin#example.com'},
],
start: {
date_time: '2015-05-28T09:00:00-07:00',
time_zone: 'America/Los_Angeles',
},
end: {
date_time: '2015-05-28T17:00:00-07:00',
time_zone: 'America/Los_Angeles',
}
}
event = calendar.insert_event('primary', event, send_notifications: true)
and don't forget to run this first:
gem install google-api-client
and also to create these files with the correct authentication information
credentials.json
token.yaml
and to figure out your user_id.
