Create a new project in rails older version

Question

I have rails version 3.2.1 in my machine. The other versions installed are 3.0, 3.0.3. Whenever i run

 rails new PROJECT_NAME

command ,the project gets created in version 3.2.1. I want to create the project in version 3.0.3.

What should i do?

Answer 1

you can create new app with older version

rails _3.0.3_ new appname 

but you may get error as

/usr/local/lib/ruby/site_ruby/1.9.1/rubygems.rb:316:inbin_path': can't find gem railties (["3.0.3"]) with executable rails (Gem::GemNotFoundException) from /usr/local/bin/rails:19:in'

so

again install rails gem

sudo gem install rails -v="3.0.3"

now you can do

rails _3.0.3_ new app

it will work fine

thank you

Answer 2

You could use something like RVM and install the other rails versions in a different gemset. Then select the gemset with an older rails version and your rails command should be from the older version.

Alternatively you should be able to use

rails _VERSION_ new myapp
