从 gems Mac 10.6 安装 mysql 时出错

Question

我见过这个问题的变体，但没有一个是正确的答案（到目前为止）。

我正在尝试从 ruby​​gems 安装 mysql 并得到以下结果：

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

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/mysql-2.8.1 for inspection.
Results logged to /Library/Ruby/Gems/1.8/gems/mysql-2.8.1/ext/mysql_api/gem_make.out

我尝试过像 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config 这样的参数，但仍然得到相同的结果。

从mysql网站手动安装安装，但我无法启动它。

有什么想法吗？

看起来您已经安装了 MySQL，但没有它的开发标头。您可能需要下载并安装具有这些功能的版本。

我非常喜欢使用 MacPorts 来执行此操作，尽管这会给您留下一个稍微不规则的名称，例如MacPorts 将其称为 mysql_config5。我通常通过符号链接来修复名称：

ln -s /opt/local/bin/mysql_config5 /opt/local/bin/mysql_config

您可以对任何具有不常见名称的二进制文件执行此操作，例如 mysql5 和 mysqladmin5。
