调用未定义的方法Illuminate \ Database \ Eloquent \ Collection :: useAsCallable（）“

I am getting the following error on a laravel site:

Call to undefined method Illuminate\Database\Eloquent\Collection::useAsCallable() on line 72 of /var/www/html/vendor/laravel/framework/src/Illuminate/Database/Eloquent/Collection.php

This only seems to happen on the staging server and I cannot reproduce on my local machine. I have deleted the vendor directory and completely rebuilt it via composer, cleared all caches, ran composer dump-autoload and nothing seems to resolve it.

Digging into the source I can confirm that Illuminate\Database\Eloquent\Collection extends Illuminate\Support\Collection and the method useAsCallable() exists in the extended class. It is like it isnt loading it our something.

Any ideas?

Wierdly enough, I have noticed that most of such troubles from OctoberCMS arise out of 1 thing more often than not. -> FILE PERMISSIONS. This is especially true if using git to deploy.

set proper permissions: sudo chmod -R 777 octoberProject/ Then retry running the app.

Let us know if this helps.
