Ruby on rails 从gems Mac 10.6安装mysql时出错

我见过这个问题的各种变体，但到目前为止没有一个是正确的答案

我正在尝试从rubygems安装mysql，并获得以下信息：

    Building native extensions.  This could take a while...

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

从mysql网站手动安装，但我无法启动它

有什么想法吗？

看起来你已经安装了MySQL，但是你没有它的开发头。您可能需要下载并安装具有这些功能的版本

我非常喜欢用它来做这件事，不过这会给你留下一个稍微不规则的名字，MacPorts称之为mysql\u config5。我通常将此符号链接以修复名称：

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

您可以对任何具有不寻常名称的二进制文件（如mysql5和mysqladmin5）执行此操作。

我将其用于Rails开发初学者。愚蠢的问题，这对MacPorts来说不是问题吗？MacPorts是一个基于源代码的安装，所以您可以将所有开发头作为包的一部分。许多二进制安装缺少这种节省空间的功能。你也可以试试看什么最适合你。
