Why does gibbon throw 'uninitialized constant Gibbon::API (NameError)'
问题 I'm trying to add the gibbon gem into a Rails 3.2 app. I've followed the instructions, and set up a gibbon.rb initializer with the following Gibbon::API.api_key = ENV["MAILCHIMP_API_KEY"] Gibbon::API.timeout = 15 Gibbon::API.throws_exceptions = false The app is throwing uninitialized constant Gibbon::API (NameError) I've tried to require 'gibbon' amongst other things, but nothing seems to work. Why is the class not initialized? 回答1: Turns out I was using the wrong version of the gem. Github
