Hi John, I am trying to install this packege in laravel5.6. I followed the instructions but I am getting Call to undefined method JonnyW\PhantomJs\Client::setBinDir() for $client->setBinDir('../bin'); even Call to undefined method JonnyW\PhantomJs\Http\CaptureRequest::setCaptureFile() I might be the issue? I am using php7.0 with nginx on ubuntu.
