I use 5.7v Laravel and 7.2.1v PHP and composer last version, but when I like to create new project these errors appeared:

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.`

推荐答案

首先，停止XAMPP/Wamp，然后从您的 xampp \中删除开始的分号(; )\php \ php.ini 以下代码.

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

;extension=fileinfo

或在具有IIS的Windows中

or in windows with IIS

extension=php_fileinfo.dll

然后重新启动XAMPP/Wamp.

And then restart your XAMPP/Wamp.

注意::对于Windows，您可以在 C:\ xampp \ php \ php.ini -文件夹(Windows)或etc-Folder(在xampp-Folder内).

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).
