MySQL和Rails Server的问题

Question

最终编辑：我玩了几个不同的文件，但出现了更多错误，然后从头开始重新安装了rvm和其他所有内容，找到了一些修复程序并对其进行了编辑，最后一切正常。 谢谢你们每一个人的帮助

编辑：我注意到它说库未加载：/usr/local/mysql-5.5.10-osx10.6-x86_64/lib/libmysqlclient.18.dylib（LoadError）

但是我有mysql 5.5.11，我该如何解决？

我确实搜索了过去3个小时，但没有发现任何有效的方法

当我尝试启动服务器或生成模型时，也会发生相同的错误

我有捆绑器和mysql2 gems。

生成器（2.1.2）捆绑程序（1.0.12）erubis（2.6.6）i18n（0.5.0）邮件（2.2.17）MIME类型（1.16）mysql2（0.2.7）

我得到以下输出：

Answer 1

每当遇到加载错误时，都应确保已安装并安装了所有依赖项。

1. 确保您的Gemfile中有gem mysql2 。
2. 如果您尚未在gem install bundler安装bundler，请进行gem install bundler 。
3. 运行bundle （与bundle install相同）。

然后尝试再次运行服务器。

Answer 2

带有Rails 3.0.3的mysql2给出了一些错误，因此请尝试使用3.0.6更新Rails版本

它工作正常，所以尝试
