我在我的开发环境中将webrick更改为puma，但我无法运行rails服务器，查看我的错误：美洲狮错误：无法分配请求的地址 - 绑定（2）为“10.0.2.2”端口3000（Errno :: EADDRNOTAVAIL）

好吧，我知道problem is in my environment并且使用该编辑部地址存在另一个proccess。但我怎么能解决这个问题？你看我的netstats

重要我调查的问题，发生在puma-3.6.0/lib/puma/binder.rb @ line 260 Puma::Binder#add_tcp_listener. exactly in *TCPServer.new(host, port)*

def add_tcp_listener(host, port, optimize_for_latency=true, backlog=1024) 
    if host == "localhost" 
    localhost_addresses.each do |addr| 
     add_tcp_listener addr, port, optimize_for_latency, backlog 
    end 
    return 
    end 

    host = host[1..-2] if host and host[0..0] == '[' 
    s = TCPServer.new(host, port) 
    if optimize_for_latency 
    s.setsockopt(Socket::IPPROTO_TCP, Socket::TCP_NODELAY, 1) 
    end 
    s.setsockopt(Socket::SOL_SOCKET,Socket::SO_REUSEADDR, true) 
    s.listen backlog 
    @connected_port = s.addr[1] 

    @ios << s 
    s 
end
  • 所以，localhost_addresses包含2个值["127.0.0.1", "10.0.2.2"]
  • 当“10.0.2.2”作为参数传递时发生错误。为什么2地址？

的localhost_addresses方法

def localhost_addresses 
    addrs = TCPSocket.gethostbyname "localhost" 
    addrs[3..-1].uniq #- ['10.0.2.2'] 
end

第一次调用'localhost'，第二次调用'“127.0.0.1”'，第三次调用'“10.0.2.2”'？ – Aleksey

@Aleksey'“127.0.0.1”' - >''10.0.2.2“' - >'”10.0.2.2“' –

如果'localhost_addresses'只包含两个值，这不奇怪吗？ – Aleksey

好像你在你的localhosts 10.0.2.2。
您可以在/etc/hosts中查看。
它可能看起来像

... 
127.0.0.1  localhost 
10.0.2.2  localhost 
...

如果您不需要10.0.2.2这里，你不知道为什么你得到它（你的情况=）），您可以删除此行，并尝试再次运行rails s。
也许你将不得不重新启动你的网络系统，或者你可以重新启动。

另一种方法是在特定主机上运行轨道服务器一样

rails s -b 127.0.0.1

我不知道问题的确切原因，但我希望它可以帮助你以某种方式。
