Installing Rails with MySQL on a Mac
I recently ran into a problem with Ruby on Rails on my Mac when trying to execute the following command in a new Rails project.
rake db:migrate
The error I received was as follows.
dyld: NSLinkModule() error
dyld: Library not loaded: /usr/local/mysql/lib/mysql/libmysqlclient.15.dylib
Referenced from: /usr/local/lib/ruby/gems/1.8/gems/mysql-2.7/lib/mysql.bundle
Reason: image not found
Trace/BPT trap
A quick Google search turned up a blog post by Peter Morris that had just the answer I needed. The relevant portion for this problem is excerpted below.
This is because the latest version of MySql has changed a path from lib/mysql to just lib/. To fix this problem you need to type the following (it’s all one line):
sudo install_name_tool -change /usr/local/mysql/lib/mysql/libmysqlclient.15.dylib /usr/local/mysql/lib/libmysqlclient.15.dylib /usr/local/lib/ruby/gems/1.8/gems/mysql-2.7/lib/mysql.bundle
Thanks, Peter!
