最新版RoR+MySQL出现的问题
Ruby 1.9.2 + Rails 3.0.3 + MySQL 5.1
先安装的Ruby 1.9.2，后安装的MySQL 5.1。把MySQL装完后bin目录下的“libmySQL.dll”拷贝到Ruby装完后的bin目录下。
MySQL的gem为mysql2 (0.2.6 x86-mingw32)
创建新项目时命令如下：
rails new simple_cms -d mysql
运行时Framework Trace如下：

怎么回事呢？
[解决办法]
好像还要
gem install mysql
[解决办法]
你的错误提示里没有你说的 can't convert Fixnum into String。 如果单凭这个提示就是说不能从String型转化为Fixnum型。 具体你要看下是哪一步提示的
