我已经为此纠结了一段时间。
我已经在我的雪豹机器上安装了Rails 3, gem, mysql。一切都很顺利，直到我创建了我的第一个项目并试图运行
rails server
在运行这个我得到:
jontybrook$ rails server

据我所知，问题是与mysql2宝石。MySQL似乎运行良好，我的Gemfile引用mysql2，我的数据库。Yml文件似乎也可以。
错误中提到
Reason: image not found - /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle
然而,
jontybrook$ cd /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2
jontybrook$ ls
client.rb em.rb error.rb mysql2.bundle result.rb
MySQL2。捆绑在那里!?
如果我使用旧的mysql gem, WEBrick启动正常。但这并不理想，不是吗?
谷歌能给我的我都试过了!任何帮助都非常感激。
