i want to install a laravel admin package -voyager version 1.3 ,so when i run this cmd $ composer require tcg/voyager i got this error always , is about the file composer.json
Using version ^1.3 for tcg/voyager
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.
Problem 1
- tcg/voyager v1.3.0 requires intervention/image ^2.4 -> satisfiable by intervention/image[2.4.0, 2.4.1, 2.4.2, 2.4.3, 2.5.0, 2.5.1].
- tcg/voyager v1.3.1 requires intervention/image ^2.4 -> satisfiable by intervention/image[2.4.0, 2.4.1, 2.4.2, 2.4.3, 2.5.0, 2.5.1].
- intervention/image 2.4.3 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
- intervention/image 2.4.2 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
- Installation request for tcg/voyager ^1.3 -> satisfiable by tcg/voyager[v1.3.0, v1.3.1].
To enable extensions, verify that they are enabled in your .ini files:
- C:\AppServ\php7\php.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
Installation failed, reverting ./composer.json to its original content.
and this is the file composer.json :
{
"name": "laravel/laravel",
"type": "project",
"description": "The Laravel Framework.",
"keywords": [
"framework",
"laravel"
],
"license": "MIT",
"require": {
"php": "^7.2",
"fideloper/proxy": "^4.0",
"laravel/framework": "^6.2",
"laravel/tinker": "^2.0"
},
"require-dev": {
"facade/ignition": "^1.4",
"fzaninotto/faker": "^1.4",
"mockery/mockery": "^1.0",
"nunomaduro/collision": "^3.0",
"phpunit/phpunit": "^8.0"
},
"config": {
"optimize-autoloader": true,
"preferred-install": "dist",
"sort-packages": true
},
"extra": {
"laravel": {
"dont-discover": []
}
}, ..
, Do you know how to solve that? my laravel version : 6.12

Answer 1

Try enabling php_fileinfo.dll in you php.ini file. Just remove ; from the below line and restart your server
;extension=php_fileinfo.dll
