Hi all,

I’ve just a new macbook and I need to work with rails 2.2 and not the  
version as installed with leopard. I updated gems to 1.3.1 without any  
trouble (using gem update --system) but when i try to install rails  
with the gem command all i get is this:

ERROR: While executing gem … (NoMethodError)  
undefined method `include?’ for nil:NilClass

Any suggestions would be much appreciated!

I have installed everything through MacPorts because it allowed me to  
better  
maintain  
my Ruby and Rails development environment even after an upgrade of Mac  
OS.  
Thus,  
I would recommend not installing anything in subdirectory /usr. At this  
time, all my  
RoR components are installed in /opt.

Good luck,

-Conrad

Thanks! However, it seems that specifying the installation path with  
gem install rails worked for some reason
