我一直在努力解决这个问题.
我在Snow Leopard机器上安装了Rails 3,gem,mysql.一切顺利,直到我创建了我的第一个项目并试图运行
rails server
运行这个我得到:
jontybrook$ rails server

jontybrook$
据我所知,问题在于mysql2 gem.MySQL似乎运行正常,我的Gemfile引用了mysql2,我的database.yml文件似乎还可以.
错误提到
Reason: image not found - /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle
但是
jontybrook$ cd …rails console由于此错误,我无法执行:

我通过自制软件安装了readline.我想继续使用rbenv而不是rvm.
感谢您阅读我的问题.
