How do i create new rails 3 app when i have already have rails 3 and 4 installed in same ruby version

Question

I don't want to install rails 3 or whatever, since i already have it somewhere in my computer. And,it runs smoothly in one of my application . There is one thing special with that app is in its Gemfile file i have

ruby '1.9.3'
gem 'rails',  '3.2.11'

I tried few things

1. I tried to run it via absolute path but still it doesn't works. might be i have used wrong path. I went to GEM_HOME / bin directory and then rails. It doesn't work. It is picking rails 4

2. I went to app which is using rails 3 and did this rails new ~/some_rails3_app. Doesn't work. It gives me this error

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

3. Created rails 4 app , changed gem version to 3.2.11 , deleted Gemfile.lock and did bundle install . Doesn't worked , giving some coffeescript version conflict error.

In case if that matters, i am using

1. Mac
2. zsh
3. rvm
4. ruby 1.9.3p484
5. Rails 4.0.3
6. Rails 3.2.11

Answer 1

Try

rails _3.2.11_ new appname
