Hi, When I try to run a script that requires “dbi” I get the following error: /usr/local/lib/ruby/site\_ruby/1.8/dbi.rb:352:in `load_driver': Unable to load driver 'Mysql' (DBI::InterfaceError) from /usr/local/lib/ruby/1.8/monitor.rb:242:in`synchronize’ from /usr/local/lib/ruby/site\_ruby/1.8/dbi.rb:282:in `load_driver' from /usr/local/lib/ruby/site_ruby/1.8/dbi.rb:233:in`\_get\_full\_driver’ from /usr/local/lib/ruby/site\_ruby/1.8/dbi.rb:219:in `connect’ The Mysql server is working fine and my Rails apps can even access it. The script itself has previously worked on other installations. I do have gem mysql-2.7 installed. ruby 1.8.7 (2008-08-11 patchlevel 72) [x86\_64-linux] Any help tracking the source of this problem down would be greatly appreciated. ---

That doesn’t mean there’s Ruby support for MySQL installed. I would guess that you need to install the mysql gem, and possibly more DBI-specific bindings for it. ---

Thanks for the reply, but as I said I did install the mysql gem already. I’ve uninstalled and reinstalled it multiple times both using gem and from source. I also have installed libdbd-mysql-ruby1.8 from the repository. Also the mysql dev library is installed. Ruby was installed from source instead of apt if that makes a difference. ---

Just ran into same problem, here is the fix: require ‘rubygems’ gem ‘dbi’ require ‘dbi’ # =\> Now the gems version gets loaded. There is another dbi.rb that acts different than the one from gems: /usr/lib/ruby/1.8/dbi.rb vs. /usr/lib/ruby/gems/1.8/gems/dbi-0.4.0/lib/dbi.rb ---
