Snow Leopard + Ruby 1.9.1 + MySQL Gem =巨大的问题

Question

我尝试了大约3-4个小时试图在雪豹上安装ruby 1.9.1的mysql gem.在我升级到雪豹之前,mysql gem曾经在1.9.1上运行得很好.我从我的机器上卸载了MySQL服务器和gem.然后我下载并安装:mysql-5.1.37-osx10.5-x86_64.dmg.我已经断言我安装的这个新版本是作为64位应用程序运行的.

我卸载了mysql gem.当我尝试使用此命令安装gem时:

env ARCHFLAGS="-arch x86_64" gem install mysql --verbose -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

我收到了这个错误:

Sean,我看到你在rvm下运行Ruby 1.9.1.我在相同的设置下遇到了同样的问题(Snow Leopard,rvm,MySQL 64位软件包).所有备用宝石(mysqlplus,kwatch-mysql-ruby等)都失败并出现相同的错误.

我怀疑MySQL安装,但一切都像系统默认Ruby下的冠军一样.所以我想知道rvm不是那种猴子扳手.

编辑:我明白了.我在升级到Snow Leopard之前安装了rvm,因此需要重新编译我的Ruby 1.9.1安装.为了更好的衡量,我从头开始重新安装了rvm.

这是我做的:

sudo gem uninstall rvm
rm -rf ~/.gem
sudo gem install rvm
rvm-install
rvm install 1.9.1
rvm 1.9.1
env ARCHFLAGS="-arch x86_64" gem install mysql

(注意:在rvm下安装gem时不能使用sudo,因为rvm通过修改$ PATH来工作.)

(注意:我将/ usr/local/mysql/bin添加到我的$ PATH中,所以在安装mysql gem时我没有必要指定任何可怕的命令行参数.)

mysql gem安装顺利.

我通过从MacPorts安装MySQL然后运行你在那里的相同gem install命令解决了这个问题.

所以,首先,从包中卸载你拥有的MySQL:

sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
rm -rf ~/Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*

如果你还没有这样做,请从这里安装MacPorts:http://www.macports.org/install.php 有一个Snow Leopard软件包.

从MacPorts安装mysql5-devel:

sudo port install mysql5-server-devel

它将完成所有依赖项,然后是MySQL.遵循安装程序建议的所有安装后步骤 - 启动项目等.它安装的MySQL是64位.

然后安装MySQL gem:

env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/opt/local/bin/mysql_config5

请注意路径在那里发生变化 MacPorts将MySQL放在不同的地方.

你应该好好去.
