我们开始在工作中使用 Sorbet 并srb init抛出一个需要yard的错误。文件仍然生成并且似乎工作正常，直到srb tc开始产生如下错误：
sorbet/rbi/todo.rbi:38: PG::Error was previously defined as a class https://srb.help/4012
38 |module PG::Error; end
^^^^^^^^^^^^^^^^
sorbet/rbi/hidden-definitions/hidden.rbi:121092: Previous definition
121092 |class PG::Error
^^^^^^^^^^^^^^^
重新生成隐藏定义，bundle exec srb rbi hidden-definitions产生与 相同的错误srb init，并且没有一个解决问题。为了确保我们的冰糕文件正确生成，找到错误的底部似乎是值得的。
使用：Ruby 2.6.5、Rails 6.1.4.1、冰糕 0.5.9115、Yard 0.9.26
重现步骤：
gem install rails
rails new srb_yard_test
cd srb_yard_test
将以下内容添加到 Gemfile
gem 'yard'
gem 'sorbet', :group => :development
gem 'sorbet-runtime'
bundle install
bundle exec srb init
输出片段srb init：

这有点令人困惑，因为 之后缺少换行符YARD::Server::Commands，所以错误实际上是：
Kernel#exit was called while requiring ruby source files
有趣的是，后续运行bundle exec srb init或bundle exec srb rbi hidden-definitions失败的位置与第一次运行略有不同，并生成略有不同的 sorbet 文件。第二次运行失败，Yard::Tags而不是YARD::Server::Commands。bundle exec srb rbi hidden-definitions失败于Naming YARD::Templates。
我已经尝试了来自https://github.com/sorbet/sorbet/issues/975的一些建议，例如require: false在院子里使用但同样的问题。
对解决方法或建议持开放态度。有一个相关的问题是，一个项目exit在加载时调用并以相同的方式中断srb init，冰糕团队的响应基本上是“你的代码正在调用 Kernel#exit，不要那样做”。
计划向 Yard 和/或 Sorbet 提出问题，但尚不清楚他们是否愿意修复它，而且我仍然不清楚 yard 代码中调用#exit文件加载的内容。
