您可能还需要设置ARCHFLAGS变量。请参阅。您需要安装mysql开发库，因为mysql gem包含与它们链接的本机代码。mac上最简单的方法是使用brew——我使用过它，它工作得非常完美，但任何好的mac软件包管理器都可以工作（或者您可以从源代码安装mysql） Brew安装： 安装后，只需键入：
sudo gem install mysql — –with-mysql-config=/usr/local/mysql/bin/mysql_config
默认情况下，所有brew Recipient都会安装开发库。brew很棒，但是如果@jgervin还没有使用它，那么仅仅安装mysql就太麻烦了。mysql站点的二进制软件包做得很好。不需要从源代码编译或使用新的包管理系统。是的，我同意，重要的一点是除了普通的libs之外还要安装dev库。优点是brew“免费”完成这项工作。可从mysql下载的安装程序也可以为您完成这一切。它与brew一样易于安装。好吧，如果你还没有安装自制软件，这是一个很棒的建议。它不仅安装dev和headers库，还安装mysql\u config和其他mysql\u*命令。mysql周围的许多Python和Ruby脚本都需要这两种语言。MAMP仅与mysql_*一起提供，未找到标题。我执行了
brew安装mysql'，并成功安装了mysql。但是我找不到mysql开发文件sudo gem install mysql — –with-mysql-config=/usr/local/mysql/bin/mysql_config
brew install mysql
