Hi there,

I’m learning to use RoR. I’m trying to run rake to create my blank  
database, but I get this  
“rake aborted! uninitialized constant ActiveRecord ” msg  
I don’t know what to do about it, I’ve checked I’ve installed  
everything I need.  
If I go to the files and lines indicated in the stack error  
But it doesn’t mean anything to me, I can’t see anything wrong with  
them.  
Anyone any idea what’s going on?

Thank you,

Ana
