Question

我正在尝试在Snow Leopard Mac上运行Rails应用程序。我之前从未使用过Ruby或Rails，所以任何提示都是受欢迎的。

在终端我转到应用程序的文件夹，然后运行rails server 并收到以下错误：

Could not find gem 'mysql2 (>= 0) ruby' in any of the gem sources
listed in your Gemfile. Run `bundle install` to install missing gems.

我的gemfile看起来像：

source 'http://rubygems.org'

gem 'rails', '3.1.0'

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

group :development do
  gem 'mysql2'
end

group :production do
  gem 'pg'
  gem 'thin'
end

对于所有环境，

和database.yml都有adapter: mysql2。我已经运行了bundle install，并且从运行gem list我得到了：

mysql2 (0.3.11)

我的宝石环境是：

到目前为止，我已经过去两个多小时没有运气了。
