Fehler bei der Installation von GeoIP2: geoip2/geoip2 v2.3.1 erfordert maxmind/web-service-common

Question

Dieser Fehler tritt auf, wenn ich versuche, GeoIP2 zu installieren. Leider ist die Fehlermeldung nicht sehr gut zu verstehen und ich kann nicht herausfinden, wie ich das beheben kann. Es ist klar, dass etwas fehlt, aber ich bin mir nicht sicher was. Ich bin nicht sehr erfahren mit Komponisten. Kann mir bitte jemand helfen, diesen Fehler zu entziffern?

    To enable extensions, verify that they are enabled in those .ini files: 
    - C:\PHP\php.ini 
    You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode. 

Installation failed, reverting ./composer.json to its original content. 

Answer 1

Nur falls jemand auf der gleichen Ausgabe stolpert ...

Die Lösung ist curl Erweiterung in php.ini Datei als letzter Teil der Fehlermeldung zu ermöglichen, schlägt vor:

Ich habe gerade ein Semikolon von ;extension=php_curl.dll entfernt und es hat funktioniert.

ich auch erforderlich, die neueste Version von GeoID (nicht 2.0 wie die Github docs vorschlagen):

composer require geoip2/geoip2:~2.4.0
