Question

我尝试运行rails S并得到以下错误。

我按照上一个帖子（http://stackoverflow.com/questions/5394873/trying-to-access-my-ruby-project-loaderror-pertaining-to-mysql）编写了以下内容，

 sudo install_name_tool -change libmysqlclient.18.dylib /usr/local/mysql-5.5.10- osx10.7-x86_64/lib/libmysqlclient.18.dylib /Users/ME/.rvm/gems/ruby-1.9.2-p290/gems/mysql2-0.3.8/lib/mysql2/mysql2.bundle

哪个什么都没做。我的意思是它经历了然后我写了这个。

sudo ln /usr/local/mysql-5.5.10-osx10.7-x86_64/bin/mysql /usr/local/mysql/bin/mysql

当我输入时，它说

 ln: /usr/local/mysql-5.5.10-osx10.7-x86_64/bin/mysql: No such file or directory

我不知道为什么。即使我启用了查看隐藏文件，我也看不到文件和目录。我不知道如何调试这个。

除非您必须使用Oracle破坏的MySQL 5.5软件包，否则最简单的解决方案是降低到5.1。那说......

当你说install_name工具“什么也没做”时，你的意思是什么？你之后再次尝试建造宝石了吗？给予“无所事事”的外观是UNIX工具的标准成功状态。

Re：ln，即使是最新版本仍标记为10.6。除非你自己重命名MySQL目录，否则它是mysql-5.5.10-osx10。 6 -x86_64。

使用Mysql2 for Ruby
