Question

这就是给我看的：

$ rails server
=> Booting Puma
=> 5.1.6 application starting in development`
=> Run 'rails server --h' for more startup options
***SIGUSR2 not implemented, signal based restart unavailable!
***SIGUSR1 not implemented, signal based restart unavailable!
***SIGHUP not implemented, signal based logs reopening unavailable!
Puma starting in single mode...
*Version 3.12.0 <ruby 2.3.3-222>, codename: Llamas in Pajamas
*Min threads: 5, max threads: 5
*Environment: development
*Listening on tcp://0.0.0.0:3000
Use Ctrl-C to stop

在此之前，我没有启动Rails服务器的任何问题，并且正在继续迁移数据库。我不确定发生了什么，我很新。预先谢谢您。类似问题的答案对我不起作用或我不理解。

Answer 1

只需说明我遇到同样的问题。
在Windows 8.1上运行。这些命令中的每一个都获得相同的错误消息：
bundler exec rails server
bundle exec rails server
rails server

错误消息：

=>正在启动Puma
  => Rails 5.1.6应用程序开始开发
  =>运行rails server -h获取更多启动选项
   *未实现SIGUSR2，基于信号的重启不可用！
  * 未实现SIGUSR1，基于信号的重启不可用！
  ***未执行SIGHUP，无法重新打开基于信号的日志！
  Puma以单模式启动...
  *版本3.12.0（红宝石2.3.3-p222），代号：睡衣中的骆驼
  *最小线程数：5，最大线程数：5
  *环境：发展
  *收听tcp：//0.0.0.0：3000

结合使用Puma和Ruby on Rails：SIGUSR2，SIGUSR1，SIGHUP未实现
