Hi,

Ruby 1.8.6  
Rails 2.1.1  
Rake 0.8.2

I’m trying to install a local copy of the ‘will\_paginate’ gem using  
“rake gems:unpack GEM=will\_paginate”, but I’m not having much luck.  
I’ve added “config.gem ‘will\_paginate’” to my config/environment.rb  
file.

But, when I run “rake gems:unpack GEM=will\_paginate”, nothing happens.  
I don’t get an error, but there’s nothing under vendor/gems when it’s  
done.

What am I doing wrong?

Thanks,

Dan

I had a similar issue (but not exactly the same) and found that the  
gem name has changed and I had to specify the source:

config.gem ‘mislav-will\_paginate’, :lib =\> ‘will\_paginate’, :source =\>  
'[http://gems.github.com](http://gems.github.com)

Maybe this will help your situation too?

Thanks for that Jeff, but it didn’t work. In fact, I can’t get it to  
work with _any_ gems.

Any suggestions?

Thanks,

Dan
