Error running all project specs in rspec: `formatted_backtrace': undefined method `backtrace'
每当我在完成所有测试用例后尝试 运行 rspec 整个项目（有超过 1000 个测试）时，我收到以下错误：

当我运行只有有限数量的测试用例时，比如一个文件或单个文件夹，一切正常。
这是我的 .rspec 文件
--color
--require rails_helper

require "rack_session_access/capybara"
RSpec.configure do |config|
end
所以没有什么可疑的，至于我
关于如何解决这个问题的任何想法？
将此添加到您的 .rspec 文件：
--require spec_helper
这保证您的 spec_helper 在每个规范之前都是必需的。
