WebBrick rails服务器错误

Question

有人能告诉我为什么我有这个错误..？！当我统治命令rails s并且我一直试图在几个端口运行它仍然无法工作！

Booting WEBrick
=> Rails 4.0.1 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server

(Errno::EADDRINUSE)

Answer 1

以前的服务器没有正确终止，因此您可以根据需要在不同的端口上运行服务器（或杀死之前的rails进程）：

bundle exec rails s -p 3001

Answer 2

尝试查找并终止rails使用的进程

lsof -wni tcp:3000
kill -9 PID
