Sweet Alert for Laravel 5.4 Error: Class '‘Alerts' not found

I'm trying to install the Sweet Alert package for Laravel: http://ift.tt/2nQ7GrI. I'm using Laravel 5.4.

I've followed all the directions exactly as outlined on the GitHub page, but I'm getting an error when I try to load any page that uses the master.blade.php template: "Class '‘Alerts' not found."

Has anyone else run into this? Is this package not compatible with v5.4?

Also, it seems like there is another Sweet Alert package for Laravel: http://ift.tt/1Ue04KE Does one replace the other? Is there any difference between the two?

Thanks
