推荐答案

您需要在您的规范源中require 'spec_helper'.

You need to require 'spec_helper' in your spec source.

你的 spec_helper 应该同时包含 rspec/rails 和 capybara/rails.

Your spec_helper should include both rspec/rails and capybara/rails in it.

但是，如果您想访问响应，则需要使用 get 而不是 visit.

You'll want to use get instead of visit if you want to access the response, however.
