GeoIP2のインストール中にエラーが発生しました：geoip2/geoip2 v2.3.1にはmaxmind/web-service-commonが必要です

Question

GeoIP2のインストール中にこのエラーが発生しています。残念ながら、エラーメッセージはあまりグーグルではありません。私はそれを修正する方法を理解できません。何かが欠落していることは明らかですが、私は何がわかりません。私は作曲家にはあまり経験がありません。誰も私がこのエラーを解読してくれますか？誰かが同じ問題時につまずく念の

    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 2

はい、ただ、カールをインストールし、それが正常にPHP5でのUbuntuについて をインストールします：

は、私はまた、ジオイドの最新バージョン（githubのドキュメントが示唆としてではない2.0）が必要 sudo apt-get install php5-curl

Ubuntuの場合php7の場合：sudo apt-get install php7.0-curl
