我一直在试图弄清楚如何让 OS X Lion 与 XAMPP 安装的 MySQL 一起使用 rails 中的 mysql2 gem。
这是我尝试过的:
- 安装了 XAMPP 开发工具包
- 安装了带有端口和 brew 的 mysql5-server。这两个我现在都卸载了。因为它没有解决问题。
- 从 DMG 文件安装 mysql5 社区版。现在卸载了,因为它没有解决问题。
- 以 tar 格式下载了 mysql5 社区版的 32 位版本。提取文件夹到“/var/mysql”
这是我正在运行以尝试安装它的命令:
gem install mysql2 -- --with-mysql-dir=/var/mysql --with-mysql-include=
/var/mysql/include --with-mysql-lib=/var/mysql/lib --with-mysql-config=
/Applications/XAMPP/xamppfiles/bin/mysql_config
我不知道如何让它发挥作用。我能想到的唯一一件事是我以某种方式没有正确指向目录。我尝试从 with-mysql-include、with-mysql-dir 和 with-mysql-lib 配置选项中删除 /include/、/mysql/ 和 /lib/。没有运气。我已经尝试将它们指向 XAMPP 安装。还是没有运气。
返回的错误是:
ERROR: Error installing mysql2:
