问题描述

我使用 http://dev.mysql.com/downloads/mysql 的安装程序安装了 MySQL 服务器.然后，如几个指南中所述，我想使用以下命令安装 mysql gem.

I installed the MySQL server with the installer from http://dev.mysql.com/downloads/mysql. Then, as explained in several guides, I wanted to install the mysql gem with the following command.

sudo gem install mysql

这不起作用并给出以下输出.

This is not working and gives the following output.

Building native extensions.  This could take a while...
ERROR:  Error installing mysql:
    ERROR: Failed to build gem native extension.

我多次重新安装了 ruby 1.9.3.XCode 命令行实用程序也已安装.我也用自制软件安装了 mysql 服务器(没有带任何东西).

I reinstalled ruby 1.9.3 several times. The XCode command line utilities are installed, too. I installed the mysql server with homebrew, too (didn't bring anything).

我还尝试了上述命令的一些选项，例如 --with-mysql-dir=/usr/local/mysql 和 --with-mysql-config=/usr/本地/mysql/bin/mysql_config.传入标志(sudo env ARCHFLAGS="-arch x86_64" gem install mysql)也无济于事.

I also tried some options for the command above, like --with-mysql-dir=/usr/local/mysql and --with-mysql-config=/usr/local/mysql/bin/mysql_config. Passing in flags (sudo env ARCHFLAGS="-arch x86_64" gem install mysql) didn't help neither.

更新:

我也尝试了mysql2 gem，出现同样的错误，可能是mysql2 gem依赖于mysql gem.

I also tried the mysql2 gem, with the result of the same error appearing, probably because the mysql2 gem is dependent on the mysql gem.

更新 2:

mkmf.log的内容:
