这个错误是突然发生的，我不确定是什么原因造成的。当我在线查看时，我注意到问题可能出在端口 3000 上的另一个服务 运行ning 上，但是当我尝试 运行 'lsof -i tcp:3000' 时，我没有得到任何结果。
在puma.rb内，我定义。
port ENV.fetch("PORT") { 3000 }
rackup DefaultRackup
port ENV['PORT'] || 3000
environment ENV['RACK_ENV'] || 'development'
当我将端口值更改为诸如 8080 之类的值时，服务器将 运行。我很困惑为什么服务器不会在端口 3000 上启动。我尝试 运行 的每个命令都显示没有服务 运行ning 在该端口上。
尝试以下操作：

#1707 pts/0 Rl+ 0:07 /usr/bin/ruby2.3 bin/rails s

我知道这是一个非常古老的 post 但我不得不回答以防其他人像我一样到达这里。
当您在 puma 配置中声明 port 或 bind 命令时，它将尝试绑定到 所有 这些端口或地址。
在这种情况下，您指定了 port 两次，因此它尝试绑定到两者，而第二次将失败。
