在本地设置mySQL，无法在Rails中创建数据库

我正在尝试在本地安装mySQL。我安装了它，它正在运行，我可以启动服务器，但是当我进入我的rails应用程序（我用rails新应用程序_name-d mysql创建）并尝试运行rake db:create时，我得到一个rake中止

my.bashrc如下所示：

PATH=/usr/local/bin:$PATH
PATH=${PATH}:/usr/local/mysql/bin

echo$PATH生成：

/Users/davidtmnolan/.rbenv/shims:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/mysql/bin

我假设问题就在这条路上。感谢您的指导。

结帐。@TamerShlash的可能重复项请在这种情况下标记为重复项：）@Ven我不确定，will现在标记：）应该使用自制软件安装mysql，但不确定我为什么要破坏dyld库。
