How to get rid of uninitialized constant Omniauth

问题:

I have a fresh rails-composer omniauth application. When running tests with rspec it gives this error:

$ rspec

It gives me much trouble to debbug.

EDIT. My gem file has those:

gem 'omniauth'
gem 'omniauth-facebook'

It is a fresh app generated with rails-composer, no custom code.

回答1:

You should add require_relative 'helpers/omniauth' at the beginning of spec/support/helpers.rb - works for me.

回答2:

I was having the same error, and had to include the line

require 'omniauth'

in the beginning of the specs/spec_helper.rb file to get it working.

回答3:

I believe OmniAuth class is with capital "A". If it's not that, check your GemFile if you added the gem properly.

回答4:

omniauth gem works with other gems i.e if you want to use facebook,twitter you need to add other gems too.

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