Question

我正在努力让代客工作，但是当我 运行

composer global require cretueusebiu/valet-windows

我收到这个错误：

Your requirements could not be resolved to an installable set of packages. Installation failed, reverting ./composer.json to its original content.

  To enable extensions, verify that they are enabled in your .ini files:
    - C:\php7\php.ini
  You can also run `PHP --ini` inside terminal to see which files are used by PHP in CLI mode.

Answer 1

错误信息很清楚。 valet-windows 取决于 nategood/httpful。每个列出的 nategood/httpful 版本都依赖于 PHP's curl extension，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，启用它可能只需要取消注释

;extension=php_curl.dll

在您的 php.ini 中删除前导 ;。
