Hi

I am trying to migrate to Rails3 final release. I have the mysql2 -  
0.2.3  
gem installed.  
While installing the gem, i got two weired notices:  
Enclosing class/module ‘mMysql2’ for class Client not known  
Enclosing class/module ‘mMysql2’ for class Result not known

Now on opening up the very first page (default public.html) i am  
getting a _TypeError:  
can’t convert Fixnum into String_  
Looking at the trace ([http://pastie.org/1126756](http://pastie.org/1126756)), it seems to be a  
problem  
with mysql2 gem.

## Any suggestions on what this issue is?

Sahil D.

Has there been any response to this? I am getting the same error  
Mac OS 10.6.4  
ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-darwin10.3.0]  
rails 3.0.0

Enclosing class/module ‘mMysql2’ for class Client not known

Enclosing class/module ‘mMysql2’ for class Result not known

Any ideas on where to go from here?
