在rails 3.1RC4上使用mysql

我无法让rails 3.1RC4与mysql一起工作

我刚开发了一个新的测试应用程序，但它也失败了

我做到了：rails新博客2-d mysql

然后在我的gem文件中：gem'mysql2'

在database.yml文件中：

development:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: blog2_development
  pool: 5
  username: root
  password: password
  socket: /tmp/mysql.sock

现在当我运行rails时

我得到以下错误：

我正在使用macbook，在键入mysql时安装了mysql的32位版本——我看到的版本是：

mysql版本14.14发行版5.5.15，用于osx10.6（i386），使用readline 5.1

服务器启动了

有什么建议吗？ 当做

在查看了其他答案后，您需要将mysql gem指向您安装的库

sudo install_name_tool -change libmysqlclient.16.dylib /usr/local/mysql/lib/libmysqlclient.16.dylib ~/.rvm/gems/ruby-1.9.2-p136/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle

magic命令库是否未加载：libmysqlclient.18.dylib（LoadError）是您应该担心的一行，您是否进行了捆绑安装是的，我将向您展示我在编辑的问题中得到的内容。。。当我在我的get中键入：install_name_tool:无法打开文件：/Users/tboree/.rvm/gems/ruby-1.9.2-p136/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle（没有这样的文件或目录）我想是这样的：sudo安装工具-change libmysqlclient.16.dylib/usr/local/mysql/lib/libmysqlclient.16.dylib~/.rvm/gems/ruby-1.9.2-p180/gems/mysql2-0.3.6/lib/mysql2/mysql2.bundle成功了！！export DYLD\u LIBRARY\u PATH=/usr/local/mysql/lib:$DYLD\u LIBRARY\u PATH

sudo install_name_tool -change libmysqlclient.16.dylib /usr/local/mysql/lib/libmysqlclient.16.dylib ~/.rvm/gems/ruby-1.9.2-p136/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle
