I'm running Laravel on Digital Ocean and trying to use Mailgun. Everything is configured correctly but when I try to run my script I get the error
Symfony \ Component \ Debug \ Exception \ FatalErrorException (E_ERROR) Class 'GuzzleHttp\Client' not found
on Symfony\Component\Debug\Exception\FatalErrorException …/vendor/laravel/framework/src/Illuminate/Mail/Transport/MailgunTransport.php122
Has anybody encountered this issue?
