雪豹&x2B；Ruby 1.9.1+；MySQL Gem=巨大的问题
我花了大约3-4个小时试图在雪豹上为ruby 1.9.1安装mysql gem。在我升级到SnowLeopard之前，mysql gem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。然后我下载并安装了：mysql-5.1.37-osx10.5-x86_64.dmg。我可以断言，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。当我尝试使用以下命令安装gem时： env ARCHFLAGS="-arch x86_64" gem install mysql --verbose -- --with-mysql-config=/usr/local/mysql/bin/mysql_config env ARCHFLAGS=“-arch x86_64”gem安装mysql--verbose--with mysql config=/usr/local/mysql/bin/mysql_config 我得到了这个错误： GET 304 Not Modified: http://gems.rubyforge.org/latest_specs.4.8.gz GET 200 OK: http://gems.github.com/latest_specs.4.8.gz Installing gem mysql-2.8.1 /Users/sean/.gem/ruby/1.9.1/gems/mysql-2.8.1/COPYING /Users/sean/.gem/ruby/1.9.1/gems/mysql-2.8.1/COPYING.ja /Users/sean/.gem/ruby/1.9.1/gems/mysql-2.8.1/History.txt /Users/sean/.gem/ruby/1.9.1/gems/mysql-2.8.1/Manifest.txt /Users/sean/.gem/ruby/1.9.1/gems/mysql-2.8.1/README.txt /Users/sean/.gem/ruby/1.9.1/gems/mysql-2.8.1/Rakefile /Users/sean/.gem/ruby/1.9.1/gems/mysql-2.8.1/ext/mysql_api/extconf.rb /Users/sean/.gem/ruby/1.9.1/gems/mysql-2.8.1/ext/mysql_api/mysql.c /Users/sean/.gem/ruby/1.9.1/gems/mysql-2.8.1/extra/README.html /Users/sean/.gem/ruby/1.9.1/gems/mysql-2.8.1/extra/README_ja.html /Users/sean/.gem/ruby/1.9.1/gems/mysql-2.8.1/extra/tommy.css /Users/sean/.gem/ruby/1.9.1/gems/mysql-2.8.1/lib/mysql.rb /Users/sean/.gem/ruby/1.9.1/gems/mysql-2.8.1/tasks/gem.rake /Users/sean/.gem/ruby/1.9.1/gems/mysql-2.8.1/tasks/native.rake /Users/sean/.gem/ruby/1.9.1/gems/mysql-2.8.1/tasks/vendor_mysql.rake /Users/sean/.gem/ruby/1.9.1/gems/mysql-2.8.1/test/test_mysql.rb Building native extensions.

有什么想法吗？我通过从MacPorts安装MySQL，然后运行与上面相同的gem install命令来解决这个问题 因此，首先，从软件包中卸载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*
sudo port install mysql5-server-devel
env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/opt/local/bin/mysql_config5
您应该可以开始了。我尝试了上述所有步骤，但运气不佳，但发现了一个解决方法（或其他方法），使用mysqlplus gem而不是mysql gem：
sudo env ARCHFLAGS="-arch x86_64" gem install mysqlplus
现在，我的MySQL ruby应用程序在雪豹中非常有魅力。安装XCode是我的解决方案请看以下帖子：。它展示了如何让MySQL+RubyonRails+SnowLeopard完美运行。Sean，我看到您正在rvm下运行Ruby1.9.1。在相同的设置（雪豹、rvm、MySQL 64位软件包）下，我遇到了相同的问题。所有备用gem（mysqlplus、kwatch-mysql-ruby等）都会因相同的错误而失败 我会怀疑MySQL的安装，但在系统默认Ruby下，一切都像champ一样工作。所以我想知道rvm是不是某种意义上的活动扳手 编辑：我猜出来了。我在升级到Snow Leopard之前安装了rvm，因此我的Ruby 1.9.1安装需要重新编译。为了更好地衡量，我从头重新安装了rvm 以下是我所做的：
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
