Ruby on Rails

for what it's worth, the error message is generated in the file: gems/railties-3.2.13/lib/rails/commands.rb

There are (at least) two executable ruby scripts named "rails".  The first is found in your typical search path and should be the one that gets called when you type "rails new my_app".  The second is found, after creating your new application "my_app", in the directory "my_app/script" (rails version 3) or "my_app/bin" (rails version 4).

These ruby scripts named "rails" are not the same and, if you call the second with the "new my_app" arguments, "rails" will assume you are running inside an existing application and hurl error chunks at you.

Do this

1) type the command "which rails" and you will see the full path to what your current shell assumes to be the true rails command. 

i.e. on my system
555 > which rails
/opt/local/bin/rails
 556 >

2) type the command "wc -l `which rails`" -- if you can't figure out the quoting just use the result of step 1.  i.e. on my system "which /opt/local/bin/rails"

you should see a result that is somewhere around 23 (lines) but i'm thinking you'll see 6.  the first number is the correct system wide rails script that will let you create a new app, the second number is the rails script that is placed into "my_app/script" (or "my_app/bin") and will be used when you "rails generate ..." or other such inside your new application directory structure.

just to beat this horse to death, here's what i get when, in my home directory, i call an application (6 line) rails with new...

Can't initialize a new Rails application within the directory of another, please change to a non-Rails directory first.
Type 'rails' for help.

Im a new user - I just installed rails, following directions here:
http://rubyonrails.org/download
however, when it came time to make a rails new path/etc/etc I get this
message:
Can't initialize a new Rails application within the directory of
another, please change to a non-Rails directory first.
The only complication during the download was that I had to upgrade from
version 1.8.6 to 1.9.3, which I did after installing rails. Otherwise
Ive done nothing but follow the very simple directions.
I found this very helpful thread http://www.ruby-forum.com/topic/1780147
but when the output of ls -l shows just my usual directories. Any help
is greatly appreciated.
