From: "charles a." Date: 2011-10-10T10:57:38+09:00 Subject: Re: require -- looking in rubygems, not "." Thank you very much for the help. Could someone be so kind as to show an example of what that code should look like? I tried the following without success, all gave error messages. with the command prompt in the desktop, so the prompt says " C:\Users\Charles\Desktop , then started irb, so the prompt says irb(main):001:0 require_relative 'tr' require_relative "tr" require_relative "tr.rb" require_relative "Desktop/tr" require_relative "./tr.rb" require_relative "./tr" requre_relative "desktop/tr" and so on, approximately 30 other variations, including substituting backslashes for slashes, although in the past I have found that forward slashes work in ruby on this computer while backslashes sometimes don't. I googled "require_relative" and found some examples, it looks like the first one above should have worked. I also tried restarting the computer and doing it all over again, then tried it on a laptop with winxp. None of these worked either. Thanks in advance if someone has a minute to answer this. -- Posted via http://www.ruby-forum.com/.
