Unable to execute Laravel artisan commands

tl;dr

Run composer install in your project's root folder.

Explanation

This happens when you create a project by downloading and extracting the laravel/laravel repo from GitHub, not by using the Composer command:

composer create-project laravel/laravel your-project-name

In this case the dependencies are not installed, so the vendor folder that contains Artisan doesn't exist. Running composer install in your project's root folder will install the dependencies vendor folder.

Side note

This is independent from your problem but your Artisan command is a bit deficient. You forgot =users (the table name) from the end. Also if you create a table you dont have to specify the table name again with the --table option so this command would be enough:

php artisan migrate:make create_users_table --create=users

You don't have artisan. There are two reasons:

1. To be able to run php artisan <command> you must be in your project folder, so first move to that folder using the cd command, then you can execute the command.

2. You haven't created a Laravel project in that folder. You must create one with Composer.

Run following composer command in your root folder

composer dump-autoload
