我使用 5.7v Laravel 和 7.2.1v PHP 和 composer 最后一个版本，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]. 
    - league/flysystem 1.0.47 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
Problem 2  
    - league/flysystem 1.0.47 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.  
    - laravel/framework v5.7.9 requires league/flysystem ^1.0.8 -> satisfiable by league/flysystem[1.0.47]. 0 
    - Installation request for laravel/framework v5.7.9 -> satisfiable by laravel/framework[v5.7.9].

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.`

First of all, stop the XAMPP/Wamp and then kindly remove the starting semicolon ( ;) from your xampp\php\php.inithe following code.

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

;extension=fileinfo

And then restart your XAMPP/Wamp.

然后重新启动您的 XAMPP/Wamp。

NOTE:For Windows, you can find the file in the C:\xampp\php\php.ini-Folder (Windows) or in the etc-Folder (within the xampp-Folder).

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

The problem seems to be what the error message says - your system is missing fileinfoPHP extension. Since you're on Windows, open C:\php-7\php.inifile, search for the following line, and remove the beginning ;if exists: extension=fileinfo

问题似乎是错误消息所说的 - 您的系统缺少fileinfoPHP 扩展名。由于您在 Windows 上，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

只要取消注释extension=fileinfo在php.ini它的工作对我来说，即使没有XAMPP

In my case, I had both installed PHP and XAMPP and in my path, i pointed at C:/php/as the PHP interpreter. In C:/php/php.ini, it was ;extension=fileinfowhereas in C:/xampp/php/php.iniit was extension=fileinfo. I did two changes,

就我而言，我已经安装了 PHP 和 XAMPP，并且在我的路径中，我指的C:/php/是 PHP 解释器。在C:/php/php.ini，它是，;extension=fileinfo而在C:/xampp/php/php.ini它是extension=fileinfo。我做了两个改变，

1. Deleted C:/php/
2. Changed my path to PHP to point to c:/xampp/php/

1. 已删除 C:/php/
2. 将我的 PHP 路径更改为指向 c:/xampp/php/

The problem is now resolved

问题现已解决
