</div>

in the db/migrate directory ,there are five files(001–005),so i think  
the top version should be 5,right?

but,the problem is :

when i run the "rake migrate"command,it always migrate to VERSION  
2(NOT 5).And my schema.rb file also be modified to version 2.so  
strange.  
when i run “rake migrate version=5” command which i take the  
argument,then it succed to version 5.

how can explain the problem?

thanks

I’ve seen this bevore if you have an environment variable called  
version.
