MySQL 安装:错误:无法构建 gem 原生扩展
我正在尝试将 MySQL 安装到最新版本，因为某些安装出现问题.我运行命令 gem install mysql 并收到以下信息:
I'm trying to get MySQL installed to the latest version due to some installation going wrong somewhere along the line. I run the command gem install mysql and I receive the following:

我已经搜索并尝试了很多东西，从安装特定版本到尝试重新安装 ruby，但没有任何运气.
I've searched, and tried a whole host of things, from installing specific versions to trying to reinstall ruby without any luck.
我可能会出错的任何想法?
Any ideas where I may be going wrong?

在命令行上执行which mysql"不会返回任何内容，这意味着它无法识别它.我还安装了 MySQL 系统首选项选项，我无法阻止 MySQL 运行.现在我完全不知道该怎么办了！
doing "which mysql" on the command line returns nothing, which means it's not recognizing it. I also installed the MySQL system preferences option, and I can't stop MySQL from running. Now I'm completely stuck as what to do!
编辑编辑
我刚刚使用本指南完全重新安装了 MySQL http://hivelogic.com/articles/installing-mysql-on-mac-os-x
I've just completely reinstalled MySQL using this guide http://hivelogic.com/articles/installing-mysql-on-mac-os-x
不幸的是，这也不起作用，我仍然收到相同的错误.我什至不能在命令行中执行 mysql -uroot，我收到以下错误:
Unfortunately this didn't work either, I still receive the same errors. I can't even do mysql -uroot at the command line, I get the error of:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
所以我想我什么都试过了.
So I think I've tried everything.
**已解决*
抱歉，这不起作用的原因是 MySQL 路径.我在这里写过博客:http://www.kieransenior.co.uk/2010/02/mysql-cant-connect-using-ruby-on-rails-mac-os-x-snow-leopard/
Sorry guys, the reason for this not working was because of the MySQL paths. I've blogged on it here: http://www.kieransenior.co.uk/2010/02/mysql-cant-connect-using-ruby-on-rails-mac-os-x-snow-leopard/
推荐答案
在 OSX 上安装 mysql gem
在终端中..首先执行'locate mysql_config'然后将以下命令中的路径替换为该文件所在的位置.
in a terminal.. First do a ‘locate mysql_config’ and then replace the path in the following command with where that file is.
$ sudo gem install mysql -- —–with-mysql-config=/usr/local/mysql/bin/mysql_config
Building native extensions. This could take a while…
Successfully installed mysql-2.7
