[PrestaShop] Fatal error in module

[ValterV]

[PrestaShop] Fatal error in module file :/home/hg22ow4m/public_html/modules/ps_eventbus/ps_eventbus.php:
Class 'Symfony\Component\Dotenv\Dotenv' not found

My Prestashop is 1.6.1

How i fix that error ? I cant open modules page

[ZHSoft]

The PHP library is missing, try to update it in the command line.

composer update

 

[ValterV]

When i acess on modules page appears that message

[PrestaShop] Fatal error in module file :/home/hg22ow4m/public_html/modules/ps_eventbus/ps_eventbus.php:
syntax error, unexpected 'composer' (T_STRING), expecting function (T_FUNCTION)

Sorry im not a code guy, but im trying. I put that code on that:

 * @return void
     */
    private function loadEnv()
    {
        $dotEnv = new Symfony\Component\Dotenv\Dotenv();
        $dotEnv->load(_PS_MODULE_DIR_ . 'ps_eventbus/.env.dist');

        if (file_exists(_PS_MODULE_DIR_ . 'ps_eventbus/.env')) {
            $dotEnv->load(_PS_MODULE_DIR_ . 'ps_eventbus/.env');
        }
        composer update
    }

[Rhobur]

composer require symfony/dotenv

[ValterV]

So 

* @return void
     */
    private function loadEnv()
    {
        $dotEnv = new Symfony\Component\Dotenv\Dotenv();
        $dotEnv->load(_PS_MODULE_DIR_ . 'ps_eventbus/.env.dist');

        if (file_exists(_PS_MODULE_DIR_ . 'ps_eventbus/.env')) {
            $dotEnv->load(_PS_MODULE_DIR_ . 'ps_eventbus/.env');
        }
        $dotEnv-> composer update
    }

 

Its correct? Sorry im not a coder

[Rhobur]

"composer require symfony/dotenv" or "composer update" are to be run in the terminal while in the module's directory not in code.

[ValterV]

Thats new for me. How do you do that? Im in FTP module directory. 

Sorry my newbie question

[ValterV]

I found Prestashop error on

Unknown error na linha 422 do ficheiro /home/hg22ow4m/public_html/override/classes/Cart.php [2048] Declaration of Cart::checkQuantities() should be compatible with CartCore::checkQuantities($return_product = false)

or this is a problem because Ps event Bus?

[Rhobur]

change the /home/hg22ow4m/public_html/override/classes/Cart.php [2048] Declaration of Cart::checkQuantities() to /home/hg22ow4m/public_html/override/classes/Cart.php [2048] Declaration of Cart::checkQuantities($return_product = false)

I have a module for pre order that cause that problem. Thanks for your help
