我试图让代客泊车工作，但是当我运行时
composer global require cretueusebiu/valet-windows
我收到此错误：
您的要求无法解析为一组可安装的软件包。安装失败，将 ./composer.json 恢复为其原始内容。

To enable extensions, verify that they are enabled in your .ini files:
- C:php7php.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.
错误消息非常清楚。valet-windows取决于nategood/httpful.列出的每个nategood/httpful版本都依赖于PHP的curl扩展，而您的系统没有：
nategood/httpful 0.2.9 requires ext-curl * -> the requested PHP extension curl is missing from your system.
curl可能随您安装的任何版本的 PHP 一起提供，启用它可能只涉及取消注释
;extension=php_curl.dll
通过删除前导;在您的php.ini中。
请参阅在 Windows 10 中启用 cURL。
