laravel-permission: ErrorException : Trying to access array offset on value of type null. On fresh laravel installation.

I can’t install the package on my recent laravel project. It works fine on the previous ones. Here is the error I get

`composer require spatie/laravel-permission Using version ^3.6 for spatie/laravel-permission ./composer.json has been updated Loading composer repositories with package information Updating dependencies (including require-dev) Package operations: 1 install, 0 updates, 1 removal

Remind devs not to cache config in development Published configs can't be accessed if config is cached. Don't cache in development environment! Fixes #1464 Ref #1411 Ref #1370 — committed to spatie/laravel-permission by drbyte 4 years ago

Solution

Simple solution: delete the config/permission.php file that you added prior to installing this package.

I don’t have the permission.php file in the config folder.

it’s 7.4.2, runs on both 7.4.1 and 7.4.3

Strange.

What’s different between your environment and mine? (I’m using Valet 2.8.1, with latest composer self-update, latest composer global update, and latest brew upgrade, all updated this morning)
