I made new plugin with informations find at this post: https://luketowers.ca/blog/how-to-use-laravel-packages-in-october-cms-plugins/

I update composer.php and in vendor folder i got created files I see plugin phpclasses/evalmath in backend.

When on page i try do math operation:

function onStart() {

// instantiate a new EvalMath

    $m = new EvalMath;

        $m->suppress_errors = true;

            // set the value of x

                $m->evaluate('x = 3');

     var_dump($m->evaluate('y = (x > 5)'));

}

I got error that Class 'EvalMath' not found Class is defined in file /plugins/phpclasses/evalmath/vendor/phpclasses/evalmath/evalmath.class.php What i am doing wrong?

in file /plugins/phpclasses/evalmath/composer.json

{

  "require":

      {

            "phpclasses/evalmath": ">=1.0.0"

              },

                  "repositories":

                  [

                    {

                      "url": "https:\/\/www.phpclasses.org\/"

                    },

                    {
