From: Bert Ameche on 5 Jul 2008 16:39 I'm reading Beginning Ruby and followed the installation process , using the one-click installer for Windows from Ruby Forge. I successfully loaded fxri. Received the following message after typing irb in the Windows command prompt: 'irb' is not recognized as an internal or external command, operable program or batch file. Any suggestions on how to get this working will be greatly appreciated. -- Posted via http://www.ruby-forum.com/.
From: Bill Walton on 5 Jul 2008 16:54 Hi Bert, Have you checked your PATH? It should contain an entry to ruby/bin. If not, you'll need to add it. You might also check, just to make sure ruby itself is operable, 'ruby -v' at the command line.

As you can probably tell, I'm not a programmer. I thought the paths would be created automatically since the author of Beginning Ruby just said to type irb at the command prompt to get irb(main):001:0> and this will shows it's installed correctly. When I enter Ruby commands into fxri, the expected results appear, so that is set up correctly. How would I create a path to ruby/bin? The books I have do not go into paths unfortunately.

It's part of the way Windows command prompt windows work. Your path is a list of directories. When you enter a command at a command prompt, if the command is not built into Windows itself (like dir, or chdir), then Windows searches for the command in the directories listed in your path. You can make temporary changes to your path using the SET PATH= command, or permanent changes via the System tab in Control Panel. When you install Ruby using the One-Click Installer, the installer changes your path to include the directory in which it installs the ruby and irb commands. That change does not affect existing command prompt windows, it only affects command prompt windows that you start after running the One-Click Installer. If you continue to use an command prompt window that was open before you used the One-Click Installer, then that window is still using the old path and therefore can't find ruby or irb. If you haven't started a new command prompt window since you installed Ruby, close all of the command prompt windows you have open now and start a new one. The new path will be in effect and you should be able to run ruby and irb. Here's more information about the path. It's for WinXP but I think things are very similar in Vista: http://www.computerhope.com/issues/ch000549.htm. -- RMagick: http://rmagick.rubyforge.org/ RMagick 2: http://rmagick.rubyforge.org/rmagick2.html |
