Установка MySQL Gem с Rails 3 (Lion 10.7)

Question

Я получаю эту ошибку, когда пытаюсь установить гейм MySQL с Rails 3 на OSX 10.7 Lion. Моя рубиновая версия - рубин 1.9.2p290. Я уже установил MySQL и отлично работаю.

Building native extensions. This could take a while... 
ERROR: Error installing mysql:

Напоминаю, что у меня похожая проблема на моей ОС Lion. Попробуйте это. Я нашел его в моем ~/.bash_profile. Добавить в ваш ~/.bash_profile:

export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH 

или

export DYLD_LIBRARY_PATH=/usr/local/mysql/lib
