I recently follow the excellent tutorial at the HiveLogic site on installing Ruby on OS 10.4. [Dan Benjamin](http://hivelogic.com/articles/2005/12/01/) ruby\_rails\_lighttpd\_mysql\_tiger My Problem: is with ri and rdoc: When I first tried running ri, I got an error message saying ri / rdoc were not installed and to contact the distributor of the binary used to install ruby or if ruby had been manually installed, to run make again with directives to install rdoc. I did the latter. Now when I run ri, I get this error: Before using ri, you need to generate documentation using ‘rdoc’ with the --ri option I’ve tried running rdoc with any and all options. The result is a long wait followed by an error stating rdoc doesn’t know what to do with some random file nested deep inside one of the other apps on my system ( Flash, TextWrangler, Toast ???). ri, rdoc, ruby, are all installed in /usr/local/bin How do I run rdoc so that is doesn’t choke on non ruby files? Many thanks for any help. I’m sure I’m just missing something simple. Best, Jean-Charles ---

I don’t know how terrible it would be to go do it now on an installed ruby but you can try. Just cd to the directory with the ruby libs. to do that find out the lib dir: ruby -e ‘puts Config::CONFIG[“libdir”]’ You’ll wnat to cd to the result of that command and then cd into the directory 1.8 then you can attempt to run rdoc. Good luck ---

Thanks Logan, it worked perfectly. Who would have thought being in the right directory would help ? LOL One thing: when I used the command you suggested below, I got an error: pwrBook: ~: jnchrls-\> ruby -e ‘puts Config::CONFIG[“libdir”]’ -e:1: uninitialized constant Config (NameError) I found the 1.8 dir manually instead. Is the error a typo or something I should worry about? Thanks again for the help. J-C On Apr 5, 2006, at 1:38 PM, Logan C. wrote: You need to run rdoc in the directory with the ruby files.
