几天前，我从Mac换成了Linux(Ubuntu(，并从GitHub中的团队项目中克隆了repo。(在此之前，它在Mac上运行(。但现在，我遇到了这个问题。
我试图通过运行在本地Unix套接字(3000(上启动服务器
bundle exec puma
但它却向我展示了这些错误。

然后我试着运行
bundle exec puma -C config/puma.rb -b tcp://127.0.0.1:3001
但是服务器在没有运行的情况下立即停止。

我也尝试了这篇文章中给出的方法：地址已经在使用-bind(2((Errno:：EADDRINUSE(
像
lsof -wni tcp:3000
但没有任何迹象表明我会扼杀Pid进程。
有人能帮忙吗？
这些是我正在使用的软件版本：
- Ubuntu 18.04 LTS
- Ruby 2.6.5p114(2019-10-01修订版67812([x86_64-linux]
- 彪马4.3.3版
这是config/puma.rb 中的代码
# vars
app_dir = File.expand_path("../..", __FILE__)
shared_dir = "#{app_dir}/shared"
# Specifies the `environment` that Puma will run in.
environment ENV.fetch("RACK_ENV") { "production" }
# pidfile and state
pidfile "#{shared_dir}/pids/puma.pid"
state_path "#{shared_dir}/pids/puma.state"
# Threads for serving requests
threads 1, 16
# Workers (cpu cores)
workers ENV.fetch("WEB_CONCURRENCY") { 1 }
preload_app!
# Unix socket to for nginix reverse proxy
bind "unix://#{shared_dir}/sockets/puma.sock"
# Port for local server use
port ENV.fetch("PORT") { 3000 }

看起来您正在端口3000上运行另一个程序。运行lsof -i:3000，并在命令有一些结果时使用kill命令停止它。
