Unable to download & install laravel with composer

[quoctrung2610]

With the following composer.json:

{
"name": "laravel/laravel",
"description": "The Laravel Framework.",
"keywords": ["framework", "laravel"],
"license": "MIT",
"type": "project",
"require": {
"php": ">=5.6.4",
"laravel/framework": "5.3."
},
"require-dev": {
"fzaninotto/faker": "~1.4",
"mockery/mockery": "0.9.",
"phpunit/phpunit": "~5.0",
"symfony/css-selector": "3.1.",
"symfony/dom-crawler": "3.1."
},
"autoload": {
"classmap": [
"database"
],
"psr-4": {
"App": "app/"
}
},
"autoload-dev": {
"classmap": [
"tests/TestCase.php"
]
},
"scripts": {
"post-root-package-install": [
"php -r "file_exists('.env') || copy('.env.example', '.env');""
],
"post-create-project-cmd": [
"php artisan key:generate"
],
"post-install-cmd": [
"Illuminate\Foundation\ComposerScripts::postInstall",
"php artisan optimize"
],
"post-update-cmd": [
"Illuminate\Foundation\ComposerScripts::postUpdate",
"php artisan optimize"
]
},
"config": {
"preferred-install": "dist"
}
}

When I run this command:

php composer.phar install

or:

composer global require "laravel/installer"

I get this output:

C:\wamp\www\st>php composer.phar install

Try to force https for all resources by running composer config -g repo.packagist composer https://packagist.org - that usually helps get around such network issues.

Add this lines to your composer.json @ashish135

"repositories": [
      {
        "type": "composer",
        "url": "https://packagist.org"
      },
      { "packagist": false }
    ]

Shouldn't this be https://repo.packagist.org now instead of https://packagist.org? I've seen a lot of people refer to this comment as an official solution blessed by Composer's maintainer. It may be a good idea to update it after switching to repo.packagist.org.

Add this lines to your composer.json @ashish135

"repositories": [
      {
        "type": "composer",
        "url": "https://packagist.org"
      },
      { "packagist": false }
    ]

thank you, it work with my case.
