Can I have/use different Versions of rails in the same machine

Rails

I am actually reading a rails book that is written for rails 2.3.5. I
want to test Rails 3 beta as well. Is it possible to have such a setup
in my Mac OS leopard?

I have tried with gem list -d rails. There are many versions stored in
my mac but I don’t know how to use different version of rails while
creating new applications with rails command.

Hi,
It is possible to have different rails application on single machine.
While creating rails application u just need to specify corrosponding
rails version.
$rails version_number -d database_name application_name For ex.
$rails 2.3.5 -d mysql temp

Thank you.

Currently I have rails 2.3.8 set up in my mac. I want to install rails
3 beta as well and test it whenever I feel like.

What command I should give to install rails 3. Is it just ’ gem
install rails’ or … ?

Hi,

“gem install rails --prerelease” should install the current beta. You
also need to make sure that you have the latest version of RubyGems
with “gem update --system”.

BTW. You can install any version of rails (and any version of any gem
for that matter) specifically, by adding the "-v " to
“gem install rails”, e.g. “gem install rails -v 2.3.8”

Cheers,
Frane

Hi

first you install ruby 1.8.7 after that you type

gem install i18n tzinfo builder memcache-client rack rack-test
rack-mount erubis mail text-format thor bundler

then

gem install rails --pre .This will install rails 3.0beta

If you use rvm you gain the ability to have separate sets of gems,
named gem sets, etc.
