Maybe someone here can help me out. I’ve unpacked tzinfo in to my  
vendor/ directory using “gem unpack tzinfo” and got a  
vendor/tzinfo-0.1.1 directory as a result. How can I require this gem in  
my app? I’m trying to use a require line in my environment.rb but no  
matter what I do Rails seems to look for a locally installed copy in  
/usr/local/ instead. Any advice?

Require isn’t working because the tzinfo.rb file in tzinfo-0.1.1/lib  
doesn’t add its directory to the load path at the moment. I’ll look at  
making a change to do this in a future release.

For now, you can add tzinfo-0.1.1/lib to the load path manually using  
config.load\_paths in environment.rb:

config.load\_paths += %W( #{RAILS\_ROOT}/vendor/tzinfo-0.1.1/lib )

You should then be able to require ‘tzinfo’ and have it load the copy  
from vendor.

Thanks Philip, I’ll give this a try. Maybe you could also include this  
information on the website as well? It would probably help save some  
others from similar frustration 🙂
