ar_sendmail command not working with ruby 1.9.2

I am not able to run ar_sendmail command from my terminal. I don't think i have missed its configuration. Below is my code;

development.rb
++++++++++++++++++++++++++++++++++++++++++++++++++++
ActionMailer::Base.delivery_method = :activerecord
ActionMailer::Base.smtp_settings = {
  :address => "smtp.gmail.com",
  :port => 25,
  :domain => "www.google.com",
  :authentication => :plain,
  :user_name => "ashis.lun@gmail.com",
  :password => "kathmandu",
  :enable_starttls_auto => true
}
require "action_mailer/ar_mailer"

Gemfile 
+++++++++++++++++++++++++++
gem "ar_mailer", "1.5.1"

My Mailer
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
class P开发者_JS百科ostoffice < ActionMailer::ARMailer
  def recover_password_email(account, name, address)
    @recipients = address
    @from = "ashis.lun@gmail.com"
    @subject = "Your Account at #{account.org_name} is Ready"
    @body["subdomain"] = account.subdomain
    @body["name"] = name
    @body["org_name"] = account.org_name
    @body["password"] = password
    @body["email"] = address
  end
end

My controller
++++++++++++++++++++++++++++++++++++++++++++++++++++
def reset_password
    @user = User.find_by_email(params[:email])

    begin
      if @user
        password = get_new_password
        @user.update_attributes!(:password => password)
        Postoffice.deliver_recover_password_email(@account, @user.individual.firstname, @user.email, password)
        flash[:notice] = "Your password has been e-mailed to you. It should show up in a minute!"
        redirect_to '/sessions/new'      
      end
    rescue
      flash[:notice] = "Sorry, there was a problem resetting your password."
      redirect_to '/sessions/new'
    end
  end
end

Whenever I run ar_sendmail command I just get below message. If i hit RAILS_ROOT in console then I it shows /Users/me/Dev/a5his

ar_sendmail must be run from a Rails application's root to deliver email.

/Users/me/Dev/a5his does not appear to be a Rails application root.

Thanks in advance <><

How about using Delayed Job? I've used ar mailer in the past and find delayed job a much better solution.

Not sure if it'll make a difference, but it says here to put

require "action_mailer/ar_mailer"

in environment.rb, not development.rb or production.rb. Other than that, I can't see anything you missed.

Try ar_sendmail --chdir /Users/me/Dev/a5his or changing into the root of your rails app before running the command

ar_sendmail must be run from a Rails application's root to deliver email. /Users/me/Dev/a5his does not appear to be a Rails application root.

Are you running the command in the application's root?

try

cd #{Rails.root.to_s} && bundle exec ar_sendmail_rails3 -e production

If you look at the source (shown below), this message is displayed if loading config/environment fails. One instance of this I ran into was where a dependency was unmet, which was causing an exception to fire when config/environment was being loaded. To address this, you can use an irb session and try requiring config/environment to see what error may be causing the require to fail.

Dir.chdir options[:Chdir] do
  begin
    require 'config/environment'
  rescue LoadError
    usage opts, <<-EOF
  #{name} must be run from a Rails application's root to deliver email.
  #{Dir.pwd} does not appear to be a Rails application root.
      EOF
  end
end
