As the subject, I am not able to get installed the rDoc for Rails 2.1.2  
Any suggestion?  
Already tried with the rdoc command and when installing the gem, even  
indicating the option to install them even if already set as default. I  
noticed the same behaviour on updating rake and all libraries related to  
Rails.  
Thanks in advance to everyone.

Hi,

Any error messages?  
Is it linux? -Are you using sudo - “sudo gem install rdoc”?

reHa,  
thanks a lot for your reply.  
I am sorry for the error, it should be: “I am unable to get the Rails  
rDoc documentation.”  
No api found in the rDoc folder. And if I start the gem server there is,  
obviously, no rdoc link active for Rails.  
I am on a Mac, with a custom Ruby and RoR installation (i.e. just  
compiled into my /usr/local/ folder)  
Any clue?
