I’m use Ruby 1.9 via rvm and Rails 2.3.3. I’m on OS X 10.5 and I have
the mysql 2.8.1 gem installed. When I run rake on my rails app, I get
the error “wrong argument type Mysql (expected Struct)”. I can run
the app fine with script/server and script/console fine. Is anyone
else having this problem or know what might cause this problem?
Here’s the stack trace:
