运行 rails 秒后 gem 更新 returns 警告列表 - 警告：常量已初始化 Etc::SC_AIO_LISTIO_MAX

Question

我刚刚尝试使用命令 gem update 更新我的 gem 库并且更新顺利完成。

之后，我将 Gemfile 中的 rails 项目的版本从 6.0.1 更新为 6.0.3，在运行 rails s 之后，我收到了警告列表:

我通过 gem uninstall fileutils 和运行 gem update --default

卸载 fileutilis 修复了第一行问题

现在我对其余的警告行有疑问。有什么解决办法吗？

Answer 1

我在运行ning bundle update 命令之后找到了解决方案我也运行 bundle clean --force 和 rails s 命令的下一个运行全部警告消失。
