Can you check if it's in your vendors folder? If so, can you run php artisan clear-compiled? I'm guessing the library is not auto loaded for some reason. Maybe try running composer update with sudo.

I've check my vendors folder and it's there. I've already run php artisan clear-compiled, but nothing good happened.

Here's the answer:

"Add "pda/pheanstalk": "2.0.*" to your composer.json dependencies. The library is no longer bundled with the framework because they updated their tags. "

Hey Guys It worked ... Thanks Added "pda/pheanstalk": "2.0.*" Then I php artisan clear-compiled ..

Kabooom Pow pow ... :)

You really want "pda/pheanstalk": "~2.1"

Just make from your console this:

composer require "pda/pheanstalk"

(the current version of pda/beanstalk is 3.1)
