Hi All,

I have one question below:

How can I create app by specifying the rails version.

for example I have local rails gem versions (2.3.5, and 2.3.10) how I can create rails app => 2.3.10 but default rails gem point to 2.3.5.

I have google I found that by specifying rails _2.3.10_ new demo will help but is not working instead it creating new app in the name “2.3.10”

Can any help on the same.

Thanks, Senthil Srinivasan

the ‘new’ command did not exists in rails before rails 3, back then there was a different script for generators

script/generate controller

is now

rails g controller

so back then the ‘rails’ script was only for making apps, now it accepts commands like generate, destroy and more. If you want to see who to use it in rails 3 check out this link

I don't remember how to do it on rails 2 (the method you have tried is for rails 3), but I think if you type rails -h it will show you all the switches, one of which should be for specifying the version.

Ideally you should not be using rails 2 for new applications however.

3.2.7 is stable enough for you to create your application!
