如何擺脫未初始化的常量Omniauth（NameError）？

Question

我有一個新的rails-composer omniauth應用程序。 使用rspec運行測試時，會出現以下錯誤：

$ rspec

調試給我很大的麻煩。

編輯。 我的gem文件包含以下內容：

gem 'omniauth'
gem 'omniauth-facebook'

這是一個由rails-composer生成的全新應用，沒有自定義代碼。

Answer 1

您應該在spec/support/helpers.rb的開頭添加require_relative 'helpers/omniauth' spec/support/helpers.rb適用於我。

Answer 2

我遇到了同樣的錯誤，必須包含該行

require 'omniauth'

請在specs / spec_helper.rb文件的開頭進行操作。

Answer 3

我相信OmniAuth類的大寫字母為“ A”。 如果不是那樣，請檢查您的GemFile是否正確添加了gem。

Answer 4

omn​​iauth gem可與其他寶石配合使用，即，如果您想使用facebook，還需要添加其他寶石。

  gem 'omniauth'
  gem 'omniauth-twitter'
  gem 'omniauth-facebook'
