From: Unnsse Khan Date: 2005-10-14T08:45:15+09:00 Subject: Re: Problem with IRB and some sample code... Ezra, I followed your instructions, word for word... 2 things: 1. The IRB tab completion still isn't working (maybe its not meant to be on OS X) 2. When I tried invoking gem, this is what happened: Last login: Thu Oct 13 16:33:54 on ttyp1 Welcome to Darwin! Raven:~ untz$ gem /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in `require__': No such file to load -- syck (LoadError) from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb: 21:in `require' from /usr/lib/ruby/1.8/yaml/syck.rb:5 from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb: 21:in `require__' from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb: 21:in `require' from /usr/lib/ruby/1.8/yaml.rb:9 from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb: 21:in `require__' from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb: 21:in `require' from /usr/lib/ruby/site_ruby/1.8/rubygems/package.rb:6 from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb: 21:in `require__' from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb: 21:in `require' from /usr/lib/ruby/site_ruby/1.8/rubygems/builder.rb:1 from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb: 21:in `require__' from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb: 21:in `require' from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:61:in `manage_gems' from /usr/bin/gem:4 Raven:~ untz$ The IRB tab completion was a nice feature that I am missing out on, but what's sad is that a crucial tool such as RubyGems is broken... Thanks for your advice... Too bad, that I have this bad luck. I really can't believe that no one else knows the solution to this problem... Well, I guess I'll continue Java development, instead of learning this language which supposedly has a "great community"... Many, many thanks! -Unnsse On Oct 13, 2005, at 4:17 PM, Ezra Zygmuntowicz wrote: > OK here is a numbered list of steps to reinstall ruby from source > over your old ruby install at /usr/bin/ruby. > > 1.
