Hey everybody! Today I tried installing typo using “sudo gem install  
typo” and my machine spat this back at me:

ERROR: While executing gem … (NoMethodError)  
undefined method `refresh’ for #Hash:0x1108328

Anyone know what this is? Or how I can fix it?

Thanks

locate the file ‘source\_cache’ and delete it

on my system…

# locate source\_cache

/usr/lib/ruby/gems/1.8/source\_cache

rm /usr/lib/ruby/gems/1.8/source\_cache

I don’t have it. Turns out I’m running 1.6.  
Perhaps that’s the real problem. I will attempt to update my ruby  
installation.  
Thanks!
