我遇到了这个问题中描述的确切问题:MYSQL安装问题。不幸的是,没有一个答案对我有帮助(并且它已关闭)。
我尝试学习 Ruby on Rails,但没有让 MySQL 工作(所以它与编程相关)。
我输入:rake db:create
并得到:
!!!The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql.
rake aborted!
no such file to load -- mysql

正如它告诉我的那样,我尝试过sudo gem install mysql

我也尝试过这个命令sudo gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
并得到同样的错误!
我能做些什么?我只想将我的数据库迁移到 MySQL 服务器!
谢谢你的帮助,梅克斯
Update:
感谢大家的热烈响应!是的,我在雪豹上。
我从这里下载了mysqlhttp://dev.mysql.com/downloads/mysql/5.1.html#macosx-dmg并安装了它。
然后我按照 Hivelogic 的指南进行 mysql 安装。
当我现在输入:sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
or sudo gem istall mysql
or sudo gem install mysql -- --with-mysql-dir=/usr/local/mysql
我会得到:
