can't install smartermeter ruby gem

[tels7ar]

I get the same failure on both mac os 10.6 and on linux (Debian Squeeze):

$ ruby -v
ruby 1.8.7 (2010-08-16 patchlevel 302) [x86_64-linux]
$ uname -a
Linux 2.6.32-5-amd64 #1 SMP Wed Jan 12 03:40:32 UTC 2011 x86_64 GNU/Linux
$ sudo gem install smartermeter
ERROR:  While executing gem ... (NoMethodError)
  undefined method `call' for nil:NilClass

is there something obvious I'm missing? Is the problem the version of ruby I'm using? I note that on the mac I'm using ruby-1.8.7 too, via macports:

$ ruby -v
ruby 1.8.7 (2011-12-28 patchlevel 357) [i686-darwin10]

I will try to get ruby-19 installed on one or the other of these systems and report back if that fixes things.

[tels7ar]

Ok I got ruby-19 installed from macports and that fixed things on the mac (after I followed the nokogiri install howto). I now have 1.9.3 on my mac:

$ ruby1.9 -v ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin10]

However on the debian box I'm still stumped. I got ruby-1.9.1 installed but I'm still getting that nil:NilClass error. I ran gem install smartermeter --debug and got this:

So what am I missing now? Do you actually need something newer than the 1.9.1 I've got on debian?

[mcolyer]

Can you do gem -v on all of the boxes that don't work? I think it should work with 1.8.7 as well as 1.9.x however I think since I used a newer rubygems version when I packaged it, that it's causing issues.

I just tried grabbing 1.8.7-p357 and it came with rubygems 1.6.2 and it seems to have installed correctly.

Also you might try rvm, if you are having different versions of ruby/rubygems installed.

[tels7ar]

I suspect my problem may actually be related to using the default system rubygems-1.3.7.

Closing this out as I've update a few things since then and others have reported success.
