【中文标题】未初始化的常量 Gibbon::Request (NameError)【英文标题】：uninitialized constant Gibbon::Request (NameError) 【发布时间】：2016-10-27 15:01:44 【问题描述】：我正在尝试使用 Gibbon 和 Mailchimp 进行基本邮件列表设置。
当我启动我的 Rails 服务器rails s时，我经常收到这个错误
我什至降级到版本gem 'gibbon', '~>1.2.0'
但我的日志仍然是这样的

dadi@Dadis-iMac brainstore (AddingMailChimp) $
我一直关注这个链接http://cheshireoctopus.github.io/blog/2014/01/23/mailchimp-plus-gibbon-plus-rails-create-a-basic-sign-up-form/
还有这个http://aspiringwebdev.com/e-mail-in-rails-with-mailchimp-and-mandrill-a-comprehensive-guide/
我已经根据***帖子进行了各种修改，但似乎仍然没有任何效果。
我不知道这里发生了什么，但如果有人能给我建议会非常有帮助...
这是我的配置/initializers/gibbon.rb
require 'gibbon'
gibbon = Gibbon::Request.new(api_key: "myAPIkey")
Gibbon::API.timeout = 15
Gibbon::API.throws_exceptions = false
emailapi_controller.rb
class EmailapiController < ApplicationController
def index
end
def subscribe
@list_id = "myLISTid"
gb = Gibbon::API.new
gb.lists.subscribe(
:id => @list_id,
:email => :email => params[:email][:address]
)
end
end
Gemfile.rb
source 'https://rubygems.org'

【问题讨论】：
【参考方案1】：如果有人有兴趣，我设法通过执行以下操作来解决此问题。
在 Gemfile 中，我将 gem 'Gibbon' 更改为 gem 'gibbon', :git => 'https://github.com/amro/gibbon.git'
然后我将 emailapi_controller.rb 更改为
class EmailapiController < ApplicationController
def subscribe
@list_id = ENV["MAILCHIMP_LIST_ID"]
gibbon = Gibbon::Request.new
gibbon.lists(@list_id).members.create(
body:
email_address: params[:email][:address],
status: "subscribed"
)
respond_to do |format|
format.jsonrender :json => :message => "You have been Successfully added to the list! :)"
end
end
end
initializers/gibbon.rb 应该是这样的：
Gibbon::Request.api_key = ENV["MAILCHIMP_API_KEY"]
Gibbon::Request.timeout = 15
Gibbon::Request.throws_exceptions = false
MAILCHIMP_API_KEY 和 MAILCHIMP_LIST_ID 存储在由 figaro gem 创建的application.yml中
希望如果有人偶然发现同样的错误，这会有所帮助。
【讨论】：
【参考方案2】：Gibbon 的当前 README 指的是 Gibbon 2.x。我建议使用发布版本，而不是将您的 Gemfile 指向 github。例如
gem 'gibbon', '~>2.2.4'
【讨论】：
【参考方案3】：试试你的 Gemfile，不知道为什么 bundler 默认不这样做
gem 'gibbon', '>= 3.4.0', require: 'gibbon'
