4 个解决方案

#1

Did you have mysql installed before you upgraded to Mountain Lion? I had the same problem and this fixed it:

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

#2

You'll need a C compiler to compile some of the native extensions. (This is a Ruby requirement. You'll see this error in many more cases where a gem uses C code)

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)

Easiest way is to install Xcode.

最简单的方法是安装Xcode。

But Xcode has a lot of extra utilities that you might not need if you wan't only the compilers. There is a project (now supported by Apple) that installs only the command-line tools (various compilers and stuff) called Commandline tools for Xcode. Install this (or Xcode) and then try to install the gem.

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)只安装命令行工具(各种编译器和东西),称为Xcode的命令行工具。安装此(或Xcode),然后尝试安装gem。

I had a pain in the back trying to install mysql from command line, so I just went to the website and got it. Here is the link: http://dev.mysql.com/downloads

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

Then choose the dmg version and install it.

然后选择dmg版本并安装它。

This is absolutely the answer you did want to receive I bet (same here), but I could not do it otherwise.

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。

I'm on OS X 10.7.4

我在OS X 10.7.4上

I'm having the exact same issue, so let's see if we can work through it together. I've gone through a ton of Stack Overflow posts, and nothing anyone suggests works.

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 Installed

XCode 4.6.3已安装

Mysql 5.6.12 x64 installed from DMG

从DMG安装Mysql 5.6.12 x64

OSX 10.8.4
Ruby 2.0.0-p195

Mysql installed to /usr/local/mysql

Mysql安装到/ usr / local / mysql

Tried to install using the following with no success:

尝试使用以下内容安装但没有成功:

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 results in /usr/local/mysql-5.6.12-osx10.7-x86_64/include/mysql.h

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

/usr/local/mysql is a symlink to /usr/local/mysql-5.6.12-osx10.7-x86_64

/ usr / local / mysql是/usr/local/mysql-5.6.12-osx10.7-x86_64的符号链接

I'm going to be working on this until I can get it resolved, so if I come across anything, I'll post it.

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。
