未初始化的常数MyApp :: Application :: GeoKit（NameError）

Question

first off I'm running ruby 1.9.3-p448, and rails 4.0.3

Here's the passenger error I'm getting:

uninitialized constant MyApp::Application::GeoKit (NameError)
  /home/deployer/html/myapp/config/application.rb:12:in `<class:Application>'

And from application.rb

require File.expand_path('../boot', __FILE__)

require 'rails/all'
require 'geokit'

Bundler.require(:default, Rails.env)

module MyApp
  class Application < Rails::Application
    # line 12
    GeoKit::default_units = :miles
    # ...

I've verified that my Gemfile contains

gem 'geokit'
gem 'geokit-rails'

I've run bundle install, and the passenger error page shows both geokit, and geokit-rails under the Activated Ruby gems section:

geokit => 1.8.4

geokit-rails => 2.0.1

I'm quite new to ruby/rails, so if there are any other files I need to post, please let me know. Thanks!

Answer 1

remove this line from application.rb and put it in config/initalizer/geo_ket.rb

Geokit::default_units = :miles

it was happening because gems are loaded after line so it fails to recognise its class so it throws error.

Answer 2

Had the same issue. Gem geokit-rails3 depends on gem geokit . I was having geokit => 1.8.5 , downgrading it to geokit => 1.6.5 did the trick.
