Question

I’m trying to write a rakefile outside of a rails project.

I’ve created a new directory, added a rakefile and set a basic default task. It works.

I want to use the premailer gem so in my default task I’ve added this –

premailer = Premailer.new('http://localhost/email.html', :warn_level => Premailer::Warnings::SAFE) 

This doesn’t work, I get the following error.

uninitialized constant Object::Premailer

How do I refer to the premailer gem in my task? Should I be including it in a gemfile of sorts?

You can work without a Gemfile like this:

require 'rubygems' # only needed for ruby 1.8.7
require 'premailer'

desc "My Task"
task :my_task do
  ..
  premailer = Premailer.new(...)
  ...
end

or with a Gemfile:

require 'rubygems' # only needed for ruby 1.8.7
require 'bundler'

Bundler.setup
Bundler.require

desc "My Task"
task :my_task do
  ..
  premailer = Premailer.new(...)
  ...
end

I hope this helps.
