当我运行 Rails 时（rails s) 在我的本地主机 (OSX Mavericks) 上应用程序，我收到此错误

我不确定我是如何安装 MySQL 的，但我猜它位于名为的子文件夹中Cellar.
这是我的bash_profile好像：
MYSQL=/usr/local/mysql/bin
export PATH=$PATH:$MYSQL
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH
export PG_DUMP="/Applications/Postgres.app/Contents/MacOS/bin/"
#PATH=$PG_DUMP:$PATH
...
如何解决这个问题？
我有同样的问题。因为我是用brew安装的，所以位置DYLD改变了。尝试这个：
export DYLD_LIBRARY_PATH=/usr/local/mysql-5.1.67-osx10.6-x86_64/lib:$DYLD_LIBRARY_PATH
首先检查上面的路径是否存在，如下所示，并相应地调整导出路径：
ls -1 /usr/local/mysql-5.1.67-osx10.6-x86_64
您可能可以创建一个符号链接或其他东西。这对我来说有点烦人，但使用正确的路径为我解决了这个问题。
并且也尝试一下which mysql检查你的路径中是否有mysql。如果你没有得到任何输出，显然路径就混乱了。
