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/Ruby/Gems/1.8/gems/mysql-2.7/lib/mysql.bundle, 9): Library not loaded: /usr/local/mysql/lib/mysql/libmysqlclient.15.dylib
Referenced from: /Library/Ruby/Gems/1.8/gems/mysql-2.7/lib/mysql.bundle
Reason: image not found - /Library/Ruby/Gems/1.8/gems/mysql-2.7/lib/mysql.bundle

What's the fix?

Answering my own question for the benefit of others.

I found the fix here.

Run:

sudo install_name_tool -change /usr/local/mysql/lib/mysql/libmysqlclient.15.dylib /usr/local/mysql/lib/libmysqlclient.15.dylib /Library/Ruby/Gems/1.8/gems/mysql-2.7/lib/mysql.bundle
sudo install_name_tool -change /usr/local/mysql/lib/mysql/libmysqlclient.15.dylib /usr/local/mysql/lib/libmysqlclient.15.dylib /Library/Ruby/Gems/1.8/gems/mysql-2.7/mysql.bundle

Worked for me.

  • I had to change the order here (install_name_tool -change [old] [new]), but it worked for me too. – freitass Nov 18 '10 at 02:35
  • Didn't work for me, even when I changed the 15 to 18. Sytse's solution did work, though I have no idea what the difference is. – mcv Jul 17 '12 at 10:11

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

  • This one worked for me, unlike Gabe Hollombe's solution. No idea what the difference is. – mcv Jul 17 '12 at 10:11

Using sudo can often lead to unexpected issues. What worked for me was uninstalling the mysql2 gem and reinstalling it.

gem uninstall mysql2 bundle

If Gabe Hollombe solution doesn't works then try this

sudo install_name_tool -change libmysqlclient.15.dylib /usr/local/mysql/lib/libmysqlclient.15.dylib /Library/Ruby/Gems/1.8/gems/mysql-2.7/lib/mysql.bundle

sudo install_name_tool -change libmysqlclient.15.dylib /usr/local/mysql/lib/libmysqlclient.15.dylib /Library/Ruby/Gems/1.8/gems/mysql-2.7/mysql.bundle
