gem install mysql失败

Question

我按照http://geryit.com/blog/2011/01/installing-mysql-with-rails-on-mac-os-x-snow-leopard/上的说明进行操作,包括通过macport安装ruby.

每当我执行gem install mysql时 ,我都会收到以下错误

bash-3.2# gem install mysql
Building native extensions.  This could take a while...
ERROR:  Error installing mysql:

我该如何解决这个问题？我已经使用包文件(.pkg)安装了32位mysql,而且,我对ruby非常新...

更新4/26/11美国东部时间下午5:11 安装RVM并更新ruby到1.9.2此外,我查看了评论中发布的链接.我做了locate mysql_config ,结果是

/usr/local/mysql-5.1.56-osx10.6-x86/bin/mysql_config
/usr/local/mysql-5.1.56-osx10.6-x86/man/man1/mysql_config.1

因此,我试过 gem install mysql - -with-mysql-config=/usr/local/mysql-5.1.56-osx10.6-x86/bin/mysql_config 但它仍然无法工作......但我确实得到了新的错误信息..

非常希望感谢那些评论过的人......并且真的很感激如果能给予更多的帮助.....一直试图让安装了2天的darn mysql ...

Answer 1

目前尚未安装程序'mysql_config'.您可以输入以下命令安装它:

$ sudo apt-get install libmysqlclient-dev
$ bundle install

bundle show [mysql2] # To find the location.

Answer 2

试试这个:

gem install mysql -- --with-mysql-config=/usr/local/mysql-5.1.56-osx10.6-x86/bin/mysql_config

(注意额外的破折号)

如果这不起作用,我强烈建议使用MySQL上面提到的自制安装.你可以在这里阅读关于汤到坚果的安装:在Mac OS X 10.6上卸载Ruby on Rails

Answer 3

我在Cent OS中遇到了同样的问题,但是通过安装mysql-devel解决了这个问题

 yum install mysql mysql-server mysql-devel

Answer 4

基于这个答案,我最终编辑了我/usr/local/Cellar/mysql/5.6.12/bin/mysql_config要删除的文件-Wno-null-conversion -Wno-unused-private-field,这就是mkmf.log抱怨的错误.

我的设置是Mac OSX,使用RVM安装Ruby,使用自制软件安装MySQL.

Answer 5

通过卸载我系统上的 32 位 MySQL 解决了问题..并安装了 5.1.56 64 位。

希望这对其他和我有同样问题的人有帮助。
