I'm including in my ghunti / highcharts-php composer: "~ 3.0" and after that my autoload stops working resulting in the fatal error below, what could it be? >
Fatal error: Call to undefined method Composer \ Autoload \ ClassLoader :: setPsr4 () in /Users/my-user/my-project/dev/vendor/composer/autoload_real.php online 37
Make sure your composer and vendor/autoload.php are up to date.
Before running composer update , run the following commands:
To update the composer:
composer selfupdate
To regenerate vendor/autoload.php :
composer dump-autoload
At the end, make sure you are properly importing% required% through namespaces
Here is an example of a page that works with the instance of use
<?php
require 'vendor/autoload.php';
use Ghunti\HighchartsPHP\Highchart;
$chart = new Highchart();
var_dump($chart);
