Hi

I’d like to use the new ActionMailer that comes with Rails 3, for a  
email reminder program I am writing. I am pretty new to Ruby, and would  
like to know how I can gem install this pre-release version, so I can  
start using it.

Thanks for the help 🙂

Alex

Alex, you’ll need to use Rail 3 components. If looked at the runtime  
dependencies  
for ActionPack, you should see a pattern here:

[http://rubygems.org/gems/actionpack/versions/3.0.0.beta](http://rubygems.org/gems/actionpack/versions/3.0.0.beta)

I have gone through this, you have to

export GEM\_HOME=/usr/lib/ruby1.9.1/gems/1.9.1  
#add it to $HOME/.bashrc

Hi, I would recommend installing RVM instead of explicitly setting the  
GEM\_HOME  
environment variable. Please reference the following:

Good luck,
