安装GeoIP2时出错: geoip2/geoip2 v2.3.1需要maxmind/web-service-common

Question

我在尝试安装GeoIP2时遇到此错误。不幸的是，这个错误消息不是非常googlable的，我不知道如何修复它。很明显，有些东西丢失了，但我不确定是什么。我对作曲家不是很有经验。有人能帮我破译这个错误吗？

  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

是的，只需安装cURL，它将成功安装到带有php5的Ubuntu上：sudo apt-get install php5-curl

对于带有php7的Ubuntu：sudo apt-get install php7.0-curl

对于使用php7.4的Ubuntu：sudo apt-get install php7.4-curl

Answer 2

以防有人遇到同样的问题...

解决方案是在php.ini文件中启用curl扩展名，如错误消息的最后部分所示：

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.

我刚刚从;extension=php_curl.dll中删除了分号，它起作用了。

我还需要最新版本的GeoID (而不是github文档建议的2.0 )：

composer require geoip2/geoip2:~2.4.0
