Ich ändere Webrick zu PUMA in meiner Entwicklungsumgebung, aber ich kann Rails Server nicht ausführen, schau mein Fehler:Puma Error: Kann angeforderte Adresse nicht zuweisen - Bind (2) für "10.0.2.2" Port 3000 (Errno :: EADDRNOTAVAIL)

WICHTIG ich das Problem zu untersuchen, in 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
  • tritt also localhost_addresses enthält zwei Werte ["127.0.0.1", "10.0.2.2"]
  • Der Fehler tritt auf, wenn "10.0.2.2" als Parameter übergeben wird. Warum 2 Adresse?

Die localhost_addresses Methode

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

ist es nicht seltsam, wenn 'localhost_addresses' nur zwei Werte enthält? – Aleksey

Scheint, wie Sie 10.0.2.2 in Ihrem localhost haben.
Sie können es in /etc/hosts überprüfen.
Es

... 
127.0.0.1  localhost 
10.0.2.2  localhost 
...

aussehen können, wenn Sie hier nicht 10.0.2.2 brauchen, und Sie wissen nicht, warum Sie es bekommen (Ihr Fall =)) Sie diese Zeile entfernen und versuchen rails s erneut auszuführen.
Vielleicht müssten Sie Ihr Netzwerksystem neu starten oder Sie können neu starten.

Eine andere Möglichkeit wäre Schienen-Server auf bestimmten Host wie

rails s -b 127.0.0.1

Ich weiß nicht, genauen Gründe des Problems ausgeführt werden, aber ich hoffe, dass es Ihnen irgendwie hilft.
