I'm running Mac OSX 10.4.

I downloaded the Rails environment from locomotive.raaum.org, as suggested in Chapter 1, and installed it to my Applications folder.

When I tried to execute the rails hello command in the Terminal, I got an error message: "rails: command not found" -- but I was able to create a "hello" application from the Locomotive GUI.

Then, in Terminal, I went to my "hello" directory and entered the command:
ruby script/generate controller App,

which produced the following error:


./script/../config/boot.rb:18:in `require': No such file to load -- rubygems (LoadError)
        from ./script/../config/boot.rb:18
        from script/generate:2:in `require'
        from script/generate:2


This message doesn't mean a lot to me (maybe it will by the time I get to the end of the book...), but I gather that it can't find one of the files it needs to initialize the application. Evidently there's something wrong with the way I installed rails or the way I created the "hello" application. But I don't know what I did wrong, or what I can do to fix it.

Any suggestions?

I sometimes get the same message, look in Finder if the files do exist, sometimes ruby yells error messages and yet does its work.
