How to install Rails 2.3.2 and 2.3.4 simultaneously on Ubuntu 9.04?
I need to install Rails 2.3.2 and Rails开发者_运维问答 2.3.4 simultaneously on my Ubuntu 9.04 server. How do I do this?
When I run:
sudo gem install rails
...it installs version 2.3.4. Is there a single command I can use to also install 2.3.2 parallel to the default (latest) version?
Thanks!
use the -v option to gem:
sudo gem install rails -v=2.3.2
you'll have to do a separate install for 2.3.4 though
once installed you can specify which version you want to use for a specific rail app by editing the environment.rb file
config/environment.rb
# Specifies gem version of Rails to use when vendor/rails is not present
RAILS_GEM_VERSION = '2.3.4' unless defined? RAILS_GEM_VERSION
