您的要求无法解析为laravel的可安装程序包集

我使用5.7v Laravel和7.2.1v PHP和作曲家的最后版本,但是当我想创建新项目时,出现了这些错误:

Your requirements could not be resolved to an installable set of packages.

Problem 1
    - Installation request for league/flysystem 1.0.47 -> satisfiable by league/flysystem[1.0.47].

To enable extensions, verify that they are enabled in your .ini files:
    - C:\php-7\php.ini You can also run php --ini inside terminal to see which files are used by PHP in CLI mode.`

首先,停止XAMPP/Wamp然后;从xampp\php\php.ini中删除起始分号()以下代码.

;extension=fileinfo

然后重启你的XAMPP/Wamp.

注意:对于Windows,您可以在C:\ xampp\php\php.ini -Folder(Windows)或etc-Folder(在xampp-Folder中)中找到该文件.

问题似乎是错误消息所说的 - 您的系统缺少fileinfo PHP扩展.由于您使用的是Windows,请打开C:\ php-7\php.ini文件,搜索以下行,;如果存在则删除开头: extension=fileinfo
