Ruby Gem加载错误 mysql2/mysql2需要。

mysqlrubyrubygemsrvm

我正在尝试在OSX 10.8上设置我的Rails服务器，但我无法运行Rails服务器。 - 我目前正在使用带有mysql 5.1的Zend服务器。 - 我还安装了`brew`和`brew mysql`。 - 我使用了：
gem install mysql2 -- --srcdir=/usr/local/mysql/include --with-opt-include=/usr/local/mysql/include 服务器已经可以工作，但现在，我总是遇到以下loadError错误。
这是我的Gemfile内容：

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled

当启动rails s后：

之后我将我的 database.yml 更改如下：

development:
  adapter: mysql2
  socket: /usr/local/zend/mysql/tmp/mysql.sock
  #host: 127.0.0.1

所以我使用了本地的Zend MySQL套接字。

在我的情况下，""Can't connect to MySQL server on '127.0.0.1' (61) (Mysql2::Error)"已经消失了。

好的，我已经将我的Gemfile更改为gem 'mysql'，'~> 0.3.11'，但现在我收到了以下错误消息：“无法连接到'127.0.0.1'上的MySQL服务器(61)(Mysql2::Error)”。 - zero3nna
在我进行开发之后： 适配器：mysql2 套接字：/usr/local/zend/mysql/tmp/mysql.sock - zero3nna
