cannot load such file -- Twitter, sinatra app on Heroku

I have been able to run my app locally using sinatra, but the moment I push it to heroku, I keep getting this error:

/app/lib/initializers/twitter.rb:1:in `require': cannot load such file -- Twitter

I authorize myself using the twitter gem in a initializer file.

init.rb

APP_ROOT = File.dirname(__FILE__)
require 'sinatra'
require 'json'
require File.join(APP_ROOT,"lib","bot")
require './lib/bot'

get '/' do
    File.read(File.join( APP_ROOT, 'index.html'))
end

lib/initializers/twitter.rb

require 'Twitter'

$client = Twitter::REST::Client.new do |config|
  config.consumer_key        = ENV["CONSUMER_KEY"] 
  config.consumer_secret     = ENV["CONSUMER_SECRET"] 
  config.access_token        = ENV["ACCESS_TOKEN"] 
  config.access_token_secret = ENV["ACCESS_TOKEN_SECRET"]
end

Gemfile

ruby '2.3.1'
source 'https://rubygems.org'
gem 'rack'
gem 'twitter'
gem 'sinatra'
gem "sinatra-activerecord"
gem 'thin'
gem 'json'

config.ru

require './lib/initializers/secrets'
require './lib/initializers/twitter'
require './init'
run Sinatra::Application

Even for rake task I keep getting the below error in my local:

LoadError: cannot load such file -- active_record/railties/databases.rake
/Users/sahil/.rvm/gems/ruby-2.3.1/gems/sinatra-activerecord-2.0.11/lib/sinatra/activerecord/rake.rb:1:in `load'

(See full trace by running task with --trace)

Rakefile

require "./lib/bot"
require "sinatra/activerecord/rake"
Dir.glob('lib/tasks/*.rake').each { |r| load r}

lib/tasks/scheduler.rake

require './../bot'

desc "This task is called by the Heroku scheduler add-on"

task :fav_tweets => :environment do
    bot = Bot.new

end

How can I run a scheduler in my local first so that I can add the same to heroku?

You appear to be running:

require 'Twitter'

Note the capital T. Does it work if you run instead:

require 'twitter'

It looks like your local machine is running OS X, which typically uses a case-insensitive HFS+ filesystem.

Heroku runs on Linux systems, which typically use case-sensitive filesystems.
