"InvalidArgumentException" Please provide valid cache path in Laravel 8

Question

After leaving a project for a week and returning (without changing anything) my php artisan stopped working. This is only the case for this particular project, since php artisan works fine in other projects. When I want to run artisan commands I am getting a

[InvalidArgumentException] Please provide valid cache path:

PS C:\Users\Artur\PhpstormProjects\stuttard.de> php artisan serve

   InvalidArgumentException 

  Please provide a valid cache path.

This thread proposes to create 3 folders inside storage\framework dir:

sessions
views
cache

but I already have those:

Deleting those folders and creating them new does not help.

What can I do?

Edit:

Deleting vendor folder and running composer install produces the same exception at step @php artisan package:discover --ansi:

@ArjanShrestha I ran the command but it ends with the same `exception` when `composer` processes(?) `php artisan`. See the **Edit** section. — Artur Müller Romanov, Oct 05 '21 at 06:27
Check if your laravel version supports your current php version — Arjan Shrestha, Oct 05 '21 at 06:58
I'm using `php 8` with `Laravel 8` so it should. I tried `php 7.3` but it produced the same `exception`. — Artur Müller Romanov, Oct 05 '21 at 11:09

Laravel needs to have a caching directory in order to store the compiled blade templates.

The path is defined in config.view file as follows:

    'compiled' => env(
        'VIEW_COMPILED_PATH',
        realpath(storage_path('framework/views'))
    ),

As you might have noticed, Laravel looks at the VIEW_COMPILED_PATH env variable first (if any), if it doesn't exist, then it falls back to storage/framework/views.

If Laravel (for any reason) can't get the correct path, then it's going to throw an InvalidArgumentException (check it out framework here).

For some reason, the compiled path is wrong in your project.

It could be that the VIEW_COMPILED_PATH env variable was set to an empty/null value:

VIEW_COMPILED_PATH=''

OR

VIEW_COMPILED_PATH=

More specifically, the compiled entry returns an empty/null value, track it down and check out the returned value.

If the value is correct, then something else (such as Middleware) might have modified it.

But why composer fails?

When you run composer install/update laravel uses composer script post-autoload-dump to run php artisan package:discover command.

The php artisan package:discover command is going to rebuild the cached package manifest, therefore it hits the compiled views in order to clear them.

To solve the issue, you need to know why the config.view.compiled entry returns an invalid value.

Hey, thanks for your thorough explanation. I have no idea how that could've happened since I did not manually touch the `env variable`. I think I'll recreate the foundation of the project and copy the components. — Artur Müller Romanov, Oct 05 '21 at 12:26
IMO, you should track it down, don't create a new foundation; Software development is a learning process, spend some time, debug it and see why it's doing that. — Ahmad, Oct 05 '21 at 13:10
