可能是这篇文章与您的问题类似：库未加载：尝试在OS X 10.6上运行'rails server'时出现libmysqlclient.16.dylib错误，并显示mysql2 gem

Try this:

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

Put this in your .profile (or .bashrc) and type this command

my_term> source .profile

replace '/usr/local/mysql/lib/' by where you MySQL client is installed

Updated MySQL again from installer (say, mysql-5.5.10-osx10.6-x86_64 ).

Then MySQL2 gem: $ sudo gem install mysql2 -- --with-mysql-config=/usr/local/mysql-5.5.10-osx10.6-x86_64/bin/mysql_config

It worked for me.
