Rails - Jul 2009 - Rails on OS X problem

Hi All,

So far I have been unable to get rails working on a 10.5.6 OS X
installation. Every ''rails'' command ends with the following
error:

/Library/Ruby/Site/1.8/rubygems.rb:827:in `report_activate_error'':
RubyGem version error: ruby-openid(2.1.7 not ~> 2.0.0)
(Gem::LoadError)

I tried uninstalling and then re-installing ruby-openid, but that
doesn''t help. Working with rails on Windows and Linux machines was
never a problem, but this one has me baffled.

Groet,

Willem

What does `gem list --local ruby-openid` produce?

and "~> 2.0.0" is the pessimistic version matcher. It is equivalent
to:

">= 2.0.0", "< 2.1"

So 2.1.7 does not satisfy the requirement. Typically, this version  
matcher is used when there is a known incompatibility with a later  
version. Presumably, you can find where the ''gem
"ruby-openid", "~>
2.0.0"'' is located and determine if *that* code has a more recent
version.

Alternatively, you could try:

gem install ruby-openid -v "~>2.0.0"
