我把Ruby版本从2.5.7升级到2.7.5，把Rails从5.2.4.4升级到6.1.5。
我得到了这个错误

/home/rth/.rvm/gems/ruby-2.7.5/gems/activesupport-6.1.7.3/lib/active_support/inflector/methods.rb:287:in `const_get': uninitialized constant Web::Shared::CommercialBeyondBannerHelper (NameError)

web/shared/_commercial_beyond_banner_helper.rb：

# frozen_string_literal: true

module Web::Shared
  module CommercialBeyondBannerHelper

    def function
      # something here
    end

  end
end

这是完整的堆栈跟踪：

它仍然在旧版本中运行良好！你能帮帮我吗！谢谢！

这个错误告诉你一些代码试图使用Web::Shared::CommercialBeyondBannerHelper，但是这个模块还没有初始化，并且因为找不到它而不能自动加载。
zeitwerk是Rails 6中新的自动加载器，它会尽可能地延迟加载。
上面的链接很好地解释了交换机，并提供了如何找到潜在问题的提示（通过运行bin/rails zeitwerk:check）。
正如@Arctodus所建议的，这通常就像文件名或目录问题一样简单。
zeitwerk希望能够通过目录和文件名来查找常量，并具有一定的灵活性。
您的文件名以下划线开头：web/shared/_commercial_beyond_banner_helper.rb
zeitwerk期望只有视图部分以下划线开头。
如果这个文件是一个view partial，那么在其中定义一个模块就很奇怪了，而在其他地方调用这个模块就更奇怪了。
