gem install beaker fails for ruby 1.9.3 - Unable to resolve dependency nokogiri

[marcusphi]

It seems the current beaker version tree is inconsistent:

$ gem install beaker
ERROR:  While executing gem ... (Gem::DependencyError)
    Unable to resolve dependencies: beaker requires nokogiri (= 1.5.10); aws-sdk requires nokogiri (>= 1.4.4); fog requires nokogiri (>= 1.5.11, ~> 1.5); rbvmomi requires nokogiri (>= 1.4.1)

I'm not a ruby programmer, but if I understand things correctly it's impossible to satisfy all of these dependencies at the same time (= 1.5.10, >= 1.5.11). Note that I have none of the mentioned gems installed.

$ruby --version
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin12.5.0]

Maybe related to #292

I have been unable to reproduce.

Which version of nokogiri should I use?

@marcusphi

Try installing the following gems in the following order:

gem install nokogiri -v 1.5.10
gem install fog -v 1.19.0
gem install beaker -v 1.12.1

These should allow the gem to install.

@anodelman

Using the following ruby

ruby 1.9.3p448 (2013-06-27 revision 41675) [x86_64-darwin12.5.0]

With the following gem set list

*** LOCAL GEMS ***

bigdecimal (1.1.0)
bundler (1.3.6)
io-console (0.3)
json (1.5.5)
minitest (2.5.1)
rake (0.9.2.2)
rdoc (3.9.5)

The nokogiri resolution error will then be displayed as follows

gem install beaker
ERROR:  While executing gem ... (Gem::DependencyError)
    Unable to resolve dependencies: beaker requires nokogiri (= 1.5.10); aws-sdk requires nokogiri (>= 1.4.4); fog requires nokogiri (>= 1.5.11, ~> 1.5); rbvmomi requires nokogiri (>= 1.4.1)

[anodelman]

I created a fresh ruby 1.9.3p448 and successfully installed beaker.

@anodelman FYI: I was using crossfader for ruby version management. Mr. Shamow was using rbenv when he saw the error.
When doing a fresh install with rvm on Centos-6 I do not see the conflict.

I believe that I have the fix here #307.
