Ruby on rails 在rspec:`formatted_backtrace'；中运行所有项目规范时出错：未定义的方法`回溯'；

在完成所有测试用例后，每当我尝试为整个项目运行rspec时（有1000多个测试），我都会收到以下错误：

和

spec\u helper.rb

require "rack_session_access/capybara"
RSpec.configure do |config|
end

所以对我来说没什么可疑的

关于如何解决这个问题有什么想法吗？

将此添加到.rspec文件中：

--require spec_helper

---

这保证在每个规范之前都需要您的规范助手。

您使用什么命令来运行测试？您的

.rspec

和

spec\u helper.rb

文件中有什么？只需

rspec

即可运行所有规范。现在将用这两个文件更新问题当您使用

bundle exec rspec

时是否会得到相同的结果？效果非常好！谢谢！

--require spec_helper
