安装mysql2时发生错误(0.3.11)

Question

我是一名初学者,我从https://github.com/rubytaiwan/jobs.ruby.tw获得了一个演示.

但是当我尝试运行这个演示时,我收到了一个错误.

我跟着跑

bundle

我收到了错误

An error occurred while installing mysql2 (0.3.11), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.3.11'` succeeds before bundling.

但我可以肯定我已经安装了mysql2

而且Gemfile是

source 'https://rubygems.org'
ruby "1.9.3"

gem 'rails', '~> 3.2.12'

group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
end

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'devise', '~>2.1.3'
gem 'mysql2'

gem "babosa"
gem "rails_autolink"

gem "settingslogic"
gem "seo_helper"
gem 'open_graph_helper'
gem 'google_plus_helper'

gem 'exception_notification'

gem "mobile-fu"

gem 'capistrano', :group => "development"

gem 'rake', :group => :test

group :development do
  gem "capistrano"
  gem "magic_encoding"
  gem "annotate"
end

group :test, :development do
  gem "rspec"
  gem "rspec-rails"
  gem "simplecov"
  gem "capybara"
end

然后我试着评论这一行:

gem 'mysql2'

但我仍然得到了错误.所以我不知道为什么会出现这种错误
