Laravel安装“您的要求无法解决为一组可安装的软件包。”

Question

I'm trying to create a laravel project. I'm new to laravel and composer. My composer.json file reads

{
    "name": "jrodriguez/sapme",
    "description": "Sap Replacement Server.",
    "license": "proprietary",
    "authors": [
        {
            "name": "myname",
            "email": "myemai"
        }
    ],
    "require": {
        "laravel/framework": "~5.0"
    }
}

When I run composer diagnose it says everything is ok.

when I run composer create-project laravel/laravel --prefer-dist I get an error that my requirements can't be resolved.

Answer 1

Try

composer dump-autoload

composer install

If that doesn't help, which version of PHP are you using?

The requirement for Laravel 5.0 are:

PHP >= 5.4, PHP < 7
Mcrypt PHP Extension
OpenSSL PHP Extension
Mbstring PHP Extension
Tokenizer PHP Extension
