Autoload error when using Highchartsphp

Question

I’m including in my Komposer "ghunti/highcharts-php": "~3.0" and after that my autoload stops working resulting in the fatal error below, which could be?

Fatal error: Call to Undefined method Composer Autoload Classloader::setPsr4() in /Users/my-user/my-project/dev/vendor/Composer/autoload_real.php on line 37

Answer 1

Check your Poser and the file vendor/autoload.php are up to date.

Before executing the composer update, execute the commands below:

To update the Composer:

composer selfupdate

To generate the vendor/autoload.php:

composer dump-autoload

At the end, make sure you are importing properly the namespaces needed through use

Here is an example of a page working with the instance of Highcharts

<?php

require 'vendor/autoload.php';

use Ghunti\HighchartsPHP\Highchart;

$chart = new Highchart();

var_dump($chart);
