Laravel:require(vendor/autoload.php): failed to open stream

ERROR
requirevendor-autoload-php-failed-to-open-stream

I know that this issue has been posted many times, but for me it seems to be a different problem.

Indeed, this error

Warning: require(vendor/autoload.php): failed to open stream: No such file or directory in C:\xampp\htdocs\site_web\send_mail.php on line 3

Fatal error: require(): Failed opening required 'vendor/autoload.php' (include_path='C:\xampp\php\PEAR') in C:\xampp\htdocs\site_web\send_mail.php on line 3

appears at the begining of my code from this line:

require 'vendor/autoload.php';
So, I guess there must be a /vendor/autoload.php file somewhere in my computer (I have installed composer and ran composer require phpmailer/phpmailer).

So, I looked for this file using: dir /s autoload.php in the Windows command line, and found one here: C:\Windows\SysWOW64\vendor\autoload.php,

but for me, syswow64 folder has nothing to see with autoload.php, I don't see what I am missing here.

Solution
