Class not found exception in PHP from composer

Question

I am trying to include a package from composer, but I am receiving a class not found error.

I have tried the below possibilities.

$supermeteor = new \Supermeteor\Supermeteor('XXXXXXXX');

and

use Supermeteor\Supermeteor;
$supermeteor = new Supermeteor('xxxxxxxx');

Packages composer.json:

"psr-4": {
     "Supermeteor\\": ""
}

Packages namespace :

namespace Supermeteor;

Packages class name :

class Supermeteor() {}

Error message

Uncaught Error: Class 'Supermeteor\Supermeteor' not found in C:\path\to\my\file.php:16

What does your file structure look like? Where is the Supermeteor class file in relation to your composer.json? — Jeemusu

I just tested your package locally, and it seems to work fine for me using the same code as you provided in your question. This is how I tested it.

1. Create a new project

Create a new directory on your computer.

2. Add the package to a new project using Composer

Locate your new directory on the command line and add the package to your projects autoloader by running the below composer command.

composer require supermeteor/sdk-php

3. Use the package

Create an index.php file in the same directory as your composer.json and add the below code.

<?php
require_once __DIR__ . '/vendor/autoload.php';

use Supermeteor\Supermeteor;

$supermeteor = new Supermeteor("xxx");

4. Test the results

In the terminal window start a new php server to serve your project.

php -S localhost:8089

Now access the site via your browser at http://localhost:8089.
