I tried installing the mysql gem like so:

* * *

C:\Documents and Settings\Tim\>gem install mysql  
Select which gem to install for your platform (i386-mswin32)

1. mysql 2.7.3 (mswin32)
2. mysql 2.7.1 (mswin32)
3. mysql 2.7 (ruby)
4. mysql 2.6 (ruby)
5. Skip this gem
6. Cancel installation

Apparently, the rdoc documentation doesn’t install correctly. When I  
click on mysql’s rdoc link from the RubyGems Documentation Index, it  
just says webpage not found. Is there some way to install this  
documentation? Or failing that, is the documentation somewhere on the  
web?

Also, I am a ruby newbie so I don’t know where to find the ri  
documentation which seemingly _was_ installed. And does ri =  
reference implementation?

Many thanks to anyone who can help!

1. you can most probably generate the rdocs from the installed gem - run  
“rdoc”  
somewhere in the mysql gem directory (I don’t have my kmachine here,  
so I can’t tell you more now).

2. for ri documentation, there’s ri command, e.g. “ri Array” or  
“String#length”. You may want to try fast-ri  
([eigenclass.org](http://eigenclass.org/hiki/fastri))

I think rdoc doesn’t like trying to include html files. If anyone knows  
how to fix that, let me know. You can go to  
[MySQL/Ruby](http://www.tmtm.org/en/mysql/ruby/) and get the same thing as what the  
rdoc should have been.

Thanks, guys. With your assistance I’m without the documentation no  
longer 🙂
