前提・実現したいこと

この度、初めて質問させていただきます。

至らない点が多々あると思いますが、どうぞ宜しくお願いします。

□経緯

新たにRailsアプリケーションを作成するためにファイルを作成。

rails _5.2.1_ new bestcamp -d mysql

GemfileにGemを追加、bundle updateを実行。

source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }

ruby '2.5.1'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'

gem 'puma', '~> 3.11'
# Use SCSS for stylesheets

# Use Capistrano for deployment
# gem 'capistrano-rails', group: :development

# Reduces boot times through caching; required in config/boot.rb
gem 'bootsnap', '>= 1.1.0', require: false

group :development, :test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug', platforms: [:mri, :mingw, :x64_mingw]
end

group :development do
  # Access an interactive console on exception pages or by calling 'console' anywhere in the code.
  gem 'web-console', '>= 3.3.0'
  gem 'listen', '>= 3.0.5', '< 3.2'
  # Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring
  gem 'spring'
  gem 'spring-watcher-listen', '~> 2.0.0'
end

group :test do
  # Adds support for Capybara system testing and selenium driver
  gem 'capybara', '>= 2.15'
  gem 'selenium-webdriver'
  # Easy installation and use of chromedriver to run system tests with Chrome
  gem 'chromedriver-helper'
end

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]
#以下、追加
gem 'pry-rails'
gem 'devise'
gem 'therubyracer'
gem 'twitter-bootstrap-rails'
gem 'bootstrap-material-design', '0.1.4'
gem 'jquery-rails'
gem "font-awesome-rails"
gem 'mini_magick'
gem 'kaminari'
gem 'redcarpet'
gem 'coderay'

その後、rails sでサーバーを起動させると以下のエラーが発生。

試したこと

• リストGemfileのgem ‘tzinfo-data’からplatformsオプションを削除し、bundle updateを実行。
• リストGemfileからgem ‘tzinfo-data’の行を消去し、bundle updateを実行。
• リストGemfile.lockのファイルを削除してからもう一度bundle install。
• 手を加えていない状態のGemfileでrails sを実行すると問題なし。

情報が不足していた場合、そのご指示と、解決の手法をご教授願います。

よろしくお願いいたします。

追記

coderayのファイルが見つからないためエラーがでたと推測し、下記実行

ec2-user:~/environment/bestcamp (master) $ gem list coderay                                                                                                      

*** LOCAL GEMS ***

coderay (default: 1.1.3, 1.1.2)
ec2-user:~/environment/bestcamp (master) $ sudo gem list coderay
