(Bundler::GemRequireError) Gem错误是:未初始化的常量抽象控制器：：呈现

Question

我使用的是Rails 5.0.beta 3，一切都运行良好，在集成sendgrid-rails之后，我在运行rspec时得到了这个异常

There was an error while trying to load the gem 'sendgrid-rails'. (Bundler::GemRequireError)
Gem Load Error is: uninitialized constant AbstractController::Rendering
Backtrace for gem load error is:

我认为这只发生在Rails 5中，您对这类问题有什么经验吗？

怎么解决这个问题？顺便说一句，我也为作者提出了一个问题

谢谢

Answer 1

我刚刚解决了这个问题：

将添加到中

group :test do
  gem 'rails-controller-testing', :require => false
end

test_helper.rb 在或中要求创业板在其他人之后使用。

# Other configs
require 'rails-controller-testing'
