How to solve the problem – your requirements could not be resolved to an installable set of packages.? I have the sample detail:

{
  "name": "laravel/laravel",
  "description": "The Laravel Framework.", "keywords": ["framework", "laravel"],
  "license": "MIT",
  "repositories": [{
  "type": "vcs",
  "url": "https://github.com/Zizaco/ardent.git"
  }],
  "require-dev": {
  "phpunit/phpunit": "4.3.*"
  },
  "require": {
  "laravel/framework": "4.2.*", 
  "laravelbook/ardent": "dev-master as 2.4.0", 
  "zizaco/entrust": "dev-master", 
  "sebklaus/profiler": "dev-master", 
  "doctrine/dbal": "dev-master"
  },
  "autoload": {
  "classmap": [
  "app/commands",
  "app/controllers",
  "app/models",
  "app/database/migrations", "app/database/seeds", "app/tests",
  "app/libraries"
  ]
  },
  "scripts": {
  "post-install-cmd": [
  "php artisan clear-compiled", 
  "php artisan optimize"
  ],
  "post-update-cmd": [
  "php artisan clear-compiled", 
  "php artisan optimize"
  ],
  "post-create-project-cmd": [
  "php artisan key:generate"
  ]
  },
  "config": {
  "preferred-install": "dist"
  },
  "minimum-stability": "stable"
 }

While I was running it, I found the warning message:

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

That is my question in my midterm exam, and it is urgent. I searched the solutions on some websites, but I didn’t get it. I may miss any line or other changes. I appreciate your assistance!

    The cause: The issue stems from the reliance on branches. It’s very possible that the package zizaco/entrust used Laravel 4.2 in its master branch at one point, and that you were able to install your dependencies at that time. However, you will never be able to execute composer update and retrieve updated dependencies if this branch is updated with an incompatible version need.

    The solution: You utilize a relaxed version requirement that allows for updates that are compatible. This should be expressed as a tilde-two-number version requirement: ~1.2 would install versions 1.2.0 and higher (such as 1.2.99 or 1.2.100), as well as 1.3 and higher. If you require a certain patch release, follow these steps: Caret-three-number version ^1.2.10 installs 1.2.10 or higher, as well as 1.3 and higher.

    Using this version requirement instead of dev-master will allow you to address the most recent version that still works with Laravel 4.2 and will allow you to use released versions instead of the unstable state in the master branch. Version 1.3.0 of zizaco/entrust comes to mind, although version 1.2 would also suffice. Choose "zizaco/entrust": "~1.2."

    This command is to be executed:

    composer install –ignore-platform-reqs

    Or

    composer update –ignore-platform-reqs
