如何摆脱未初始化的常量 Omniauth (NameError)？

Question

我有一个新的 rails-composer omniauth 应用程序。使用 rspec 运行测试时会出现此错误：

$ rspec

调试起来很麻烦。

编辑。 我的 gem 文件有这些：

gem 'omniauth'
gem 'omniauth-facebook'

这是一个使用 rails-composer 生成的全新应用，没有自定义代码。

Answer 1

我遇到了同样的错误，并且必须包含该行

require 'omniauth'

在 specs/spec_helper.rb 文件的开头以使其正常工作。

Answer 2

您应该在spec/support/helpers.rb 的开头添加require_relative 'helpers/omniauth' - 适合我。

Answer 3

我相信 OmniAuth 类是大写的“A”。如果不是这样，请检查您的 GemFile 是否正确添加了 gem。

Answer 4

omniauth gem 可与其他 gem 一起使用，即如果您想使用 facebook、twitter，您还需要添加其他 gem。

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