i tried running the following from commands for creating a class Story  
and instance of class called story in Rails script console. (pg  
102/103 from Simply Rails 2 book. P. Lenz) I get the following error:

Gem::LoadError: RubyGem version error: rake-compiler(0.6.0 not ~\> 0.5.0)

I do not see any environment variables or version numbers I can make  
changes to to get RubyGem upto date.

I have tried  
Gem update  
Gem update -system  
gem install  
closed and reopend the gem console window

any suggestions are appreciated.

Thanks, Joel

My work around is “gem uninstall rake-compiler -v 0.6.0”  
Run: “Gem install rake-compiler”

next error is “could not find RubyGem : Hoe”  
So I run: “Gem install hoe”

finally after all that. back to the console window,  
“ruby script/console”  
and run the two lines to create a Story class and an instance

“class Story \< ActiveRecord::Base; end”  
“story = Story.new”

returns\> #\<Story id: nil, name: nil, link: nil, created\_at: nil,  
updated\_at: nil\>

Whew, this seems like a lot of work to get it to go.

Just ran across this thread. I was having a similar problem with  
RubyGem version error: rake-compiler(0.6.0 not ~\> 0.5.0) and was able  
to solve the issue by doing this…

gem uninstall rake-compiler -v 0.6.0

gem install rake-compiler -v 0.5.0

Hope this helps.
