Question

Nach OS Sierra Aktualisierung habe ich versucht, mit rspec spec meiner lokalen Testsuite ausgeführt wird, diese sofort brach diese Stack-Trace geben:

ich weiter im Inneren des torid gem suchten den Code-Block zu finden, die versagt:

def self.create_node_id(pid = Process.pid) 
    hostname = Socket.gethostbyname(Socket.gethostname).first 
    random = SecureRandom.hex(16) 
    FNV.new.fnv1a_64("#{hostname}-#{pid}-#{random}") 
end 

Wenn ich es mit byebug inspiziert:

(byebug)hostname = Socket.gethostbyname(Socket.gethostname).first

=>(byebug)SocketError Exception: getaddrinfo: nodename nor servname provided, or not known nil

Auch gethostname den richtigen Hostnamen zurückgibt:

(byebug)Socket.gethostname

=>(byebug) "OctobersMac"

An dieser Stelle habe ich versucht, wieder zu installieren homebrew , postgres, xcode, rvm und ruby. Ich stellte auch sicher, dass mein hostname zu OctobersMac eingestellt wurde. Es wird seltsam, dass wenn ich meine Ports nach diesem Hostnamen überprüfe, keine offen sind. Ich setze es mit scutil --get HostName und es wird korrekt zurückgegeben. Ich habe auch keine Firewalls eingerichtet.

Ich öffnete zwei andere Apps und lief rspec spec, nur um sicher zu sein, dass es nicht nur eine App war. Der kam zum ersten Mal wieder mit der exakt gleichen Fehler und der zweite bekam einen anderen Fehler, obwohl ich das Gefühl habe, es hat etwas mit der ursprünglichen Frage zu tun:

Hat jemand eine Ahnung, was hier vor sich geht? Ich bin am Ende meines Seils und Google hat nicht viel zu verwandten Themen zu Mac OsX Sierra. Vielen Dank für die Zeit, die Sie für mein Problem haben können.

Answer 1

Es scheint, dass dies ein Problem mit Sierra ist. Die Torid Gem Autoren haben eine fix. Im Kommentar stellen sie fest:

MacOS Sierra nicht immer den addrinfo Wert für die Hostnamen finden, die ein Fehler nicht passieren und torid verursachen können arbeiten.

Ich stieß auf ein ähnliches Problem mit dem Logstash Juwel, das auch fixed war. In ihrem Code haben sie einen Kommentar (in der default_source-Methode), die besagt:

# NOTE: MacOS Sierra and later are setting `.local` 
# hostnames that even as real hostnames without the `.local` part, 
# are still unresolvable. One reliable way to get an IP is to 
# get all available IP address lists and use the first one. 
# This will always be `127.0.0.1`.
