Question

我无法在我的10.8（mac osx）机器上安装mysql gem。我用自制软件安装了mysql

$ brew install mysql

然后我做了：

$sudo gem install mysql
Building native extensions.  This could take a while...
ERROR:  Error installing mysql:

任何想法该做什么？

Answer 1

在升级到Mountain Lion之前，您是否安装了mysql？我有同样的问题，这解决了它：

brew uninstall mysql
brew install mysql
gem install mysql

Answer 2

您需要一个C编译器来编译一些本机扩展。（这是Ruby的要求。在gem使用C代码的更多情况下，你会看到这个错误）

最简单的方法是安装Xcode。
但是如果您不仅仅是编译器，Xcode还有许多额外的实用程序，您可能不需要这些实用程序。有一个项目（现在由Apple支持）只安装名为Commandline tools for Xcode的命令行工具（各种编译器和东西）。安装此（或Xcode），然后尝试安装gem。

我在后面试图从命令行安装mysql时感到很痛苦，所以我只是去了网站并得到了它。这是链接：http://dev.mysql.com/downloads

然后选择dmg版本并安装它。

这绝对是你想要接受的答案我打赌（同样在这里），但我不能这样做。

我在OS X 10.7.4

Answer 4

我有完全相同的问题，所以让我们看看我们是否可以一起完成它。我已经浏览了大量Stack Overflow帖子，没有任何人建议工作。

XCode 4.6.3已安装
从DMG安装的Mysql 5.6.12 x64
OSX 10.8.4
Ruby 2.0.0-p195

将Mysql安装到 / usr / local / mysql

尝试使用以下方法安装但没有成功：

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

sudo find / -name mysql.h导致 /usr/local/mysql-5.6.12-osx10.7-x86_64/include/mysql.h

/ usr / local / mysql 是 /usr/local/mysql-5.6.12-osx10.7-x86_64

我将继续努力，直到我能解决它，所以如果我遇到任何问题，我会发布它。
