rails 3 creating new app (skel) is not compatibile with rails 2

When you have Rails 3 gem installed. It's true that you cannot create Rails 2 app with it. If you are using RVM, you can try RVM gemsets.

Other solution is that if you have Rails source git repo downloaded, switch to 2-3-stable branch and run 'ruby ~/Code/rails_repo/railties/bin/rails yourappname', this will create Rails 2 app even if you have Rails 3 gems installed.

ok, still You should consider it a bug. Rails2 gems are still in gem directory. No reason why those should not work on whole system. New "rails" command from rails3 breaks previous rails command. It should have other name, be compatibile backwards or at least fully replace old command with a new syntax - like switches to specify version 2 skel.

also new "rails new" syntax should at least allow specifing old versions inside 3.x branch like "rails _2.3.3_ dir"

Seems like an invalid ticket to me. I have multiple versions of Rails installed here, and all of the following work as expected:

# create 2.3.5 app
rails _2.3.5_ foobar

# create 3.0.0.beta4 app
rails _3.0.0.beta4_ new heythere

# create app using latest version of Rails system
rails new hello

@naox, going forward you would have to upgrade to Rails 3 with some not backward compatible changes. In that case it does not make sense for rails3 to generate Rails 2 app.

ticket invalid.

rails _2.3.5 foobar
works ok with a new "rails" command and with same command
rails 3.0.0.beta4_ new foobar

create skel for >3 you need "new" in command syntax. It does not break ceating old skel as I first observed.
