How to fix error caused by libmysqlclient.15.dylib not being loaded?

Question

I\'ve upgraded to Rails 2.2.2 and installed the MySQL 2.7 gem and am seeing this error when I try to run a migration or start the server:

dlopen(/Library/Rub         


        

Answer 1

I had to remove the directory from the old references:

sudo install_name_tool -change libmysqlclient.18.dylib
    /usr/local/mysql/lib/libmysqlclient.18.dylib
    /Library/Ruby/Gems/1.8/gems/mysql-2.7/lib/mysql.bundle

sudo install_name_tool -change libmysqlclient.18.dylib 
    /usr/local/mysql/lib/libmysqlclient.18.dylib
    /Library/Ruby/Gems/1.8/gems/mysql-2.7/mysql.bundle
