Ruby's narray gem installation error

I'm trying to install the NArray gem for Ruby to do some math functions. I'm running Ruby version 1.8.7 on a OSX Mountain Lion

When I attempt to install the NArray gem, it produces the following error: 

instance of Date needs to have method `marshal_load'

I've googled, with no luck whatsoever.

Solution

  • This seems to be due to a change in Marshal format of Date. https://github.com/rubygems/rubygems/issues/266
