I recently installed Ruby 1.8.4 on Mac OS X 10.4.7, following the instructions in http://hivelogic.com/articles/2005/12/01/ruby_rails_lighttpd_mysql_tiger Although irb starts up and runs OK, I am unable to get ri to work (either within irb or as an external command). It says: >> ri Proc /Users/rdm/.irbrc:2: warning: Insecure world writable dir /Volumes, mode 04177/usr/local/lib/ruby/1.8/yaml.rb:9:in `require': no such file to load -- stringio (LoadError) from /usr/local/lib/ruby/1.8/yaml.rb:9 from /usr/local/lib/ruby/1.8/rdoc/ri/ri_descriptions.rb:1 from /usr/local/lib/ruby/1.8/rdoc/ri/ri_reader.rb:1 from /usr/local/lib/ruby/1.8/rdoc/ri/ri_driver.rb:5 from /usr/local/bin/ri:43 => false Ignoring the /Volumes nastygram (Hey, it's a mount point!), it appears that a require is failing. Hmmm... >> $: => ["/usr/local/lib/ruby/site_ruby/1.8", "/usr/local/lib/ruby/site_ruby/1.8/powerpc-darwin8.7.0", "/usr/local/lib/ruby/site_ruby", "/usr/local/lib/ruby/1.8", "/usr/local/lib/ruby/1.8/powerpc-darwin8.7.0", "."] Looks pretty good; let's see if the file is there and readable: % cd /usr/local/lib/ruby % du -a . | grep stringio.rb 8 ./1.8/yaml/stringio.rb 16 ./gems/1.8/gems/actionmailer-1.1.5/lib/action_mailer/ vendor/tmail/stringio.rb % wc ./1.8/yaml/stringio.rb 83 175 1969 ./1.8/yaml/stringio.rb At this point, I'm tapped out.
