Hi!

I just tried installing facets-1.7.30.

I keep getting this error -

require ‘facets’  
LoadError: no such file to load – facets/core/enumerable/each\_slice  
from /usr/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:27:in  
`gem_original_require' from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in`require’  
from /usr/lib/ruby/gems/1.8/gems/facets-1.7.30/lib/facets.rb:89  
from /usr/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:33:in  
`require’  
from (irb):2

I get the same error when installing the facets gem.

Can anyone help?

Regards.

Stephen

My apologies for any inconvenience. enumerable/each\_slice is being  
deprecated. Unfortunately the ChangeLog entry for this got mangled  
somehow and said nothing but “ice” (the last three letters of of  
each\_slice). The reason is Ruby now supports each\_slice in the standard  
library. All you have to do is:

require ‘enumerator’

And I beleive as of Ruby 1.9 this will built-in functionality too and  
there will no longer be a need for the require (Can anyone verify  
that?)

Nonetheless I’ll am goging to release a minor update to facets today  
that fixes this issue. It will be a temproray patch the will just  
redirect ‘enumerable/each\_slice’ to ‘enumerator’.

One important consideration though is that Ruby’s each\_slice and  
Facets’ previous version differ in that Ruby’s will not use the block’s  
arity if no slice count is given --it will raise an Argument error  
instead. To get this behavior back use Facets’ #each\_by (maybe I’ll  
submit an RCR for this).

HTH,  
T.
