Mac OS 10.6 服务器无法安装 mysql gem

Question

我与下面链接中讨论的问题几乎相同：

安装 Mysql2 时出错gem- 10.6 Server

我已经遵循了所描述的解决方案，但我得到了这个：

sudo env ARCHFLAGS="-arch x86_64" gem install mysql2 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
Building native extensions.  This could take a while...
ERROR:  Error installing mysql2:
    ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Gem files will remain installed in /Users/angelos/.rvm/gems/ruby-1.9.2-p290/gems/mysql2-0.3.7 for inspection.
Results logged to /Users/angelos/.rvm/gems/ruby-1.9.2-p290/gems/mysql2-0.3.7/ext/mysql2/gem_make.out

此外，我还尝试指定所有 mysql 路径：

sudo env ARCHFLAGS="-arch x86_64" gem install mysql --
--with-mysql-dir=/usr/local/mysql
--with-mysql-lib=/usr/local/mysql/lib
--with-mysql-include=/usr/local/mysql/include
--with-mysql-config=/usr/local/mysql/bin/mysql_config

并且仍然收到错误

$ sudo env ARCHFLAGS="-arch x86_64" gem install mysql2 -- --with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib --with-mysql-include=/usr/local/mysql/include --with-mysql-config=/usr/local/mysql/bin/mysql_config

任何帮助赞赏。

Answer 1

您是否在链接的路径中实际安装了 mysql 头文件？你安装了包含头文件的mysql包吗？

/usr/local/mysql

我已经用 ports 安装了 mysql，我把它放在 /opt

$ find /opt -name mysql.h
/opt/local/include/mysql5/mysql/mysql.h

你可以试试

$ find /usr/local -name mysql.h

Answer 2

我回溯到 mysql 5.1.59 版本而不是 5.5，它工作得很好。

看来 gem 仍然与 MySQL 5.5.xx 不兼容
