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

Question

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.`

Answer 1

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

or in windows with IIS

extension=php_fileinfo.dll

And then restart your 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).

Answer 2

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

extension=fileinfo

or in windows with IIS

extension=php_fileinfo.dll

Answer 3

只需在php.ini取消注释extension=fileinfo ，即使没有 xampp 也对我有用

Answer 4

在我的情况下，我只是在php.ini取消注释extension=fileinfo然后它就可以工作了

Answer 5

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=fileinfo whereas in C:/xampp/php/php.ini it was extension=fileinfo . I did two changes,

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

The problem is now resolved
