我有一个无法在CircleCI上构建的项目。所有测试均通过本地测试。如果构建失败，并且我使用ssh重新运行构建，那么我可以成功连接并运行所有命令，并且所有测试都在ssh会话中通过。
bundle exec rake db:create的生成失败
我尝试在config/application.rb中重新排列require语句，但没有成功。有什么想法吗？
以下是完整的回溯：
bundle exec rake db:create --trace
rake aborted!

这可能不是一个完整的答案，但我在使用circleci/ruby:2.4.2-jessie-node映像时遇到了类似的问题。我没有深入研究，但从表面上看，加载URI::Generic类似乎有问题。
由于这个错误来自coreruby本身，我将其记为那个图像，并将图像更新为circleci/ruby:2.4.3-jessie-node，没有遇到同样的错误。
我有更多的信息，但还没有机会深入了解：
