Illuminate\Contracts\Container\BindingResolutionException

Hi guys,

I got all the way to the end of the video and attempted to update the Laravel to v8 but hitting an error when I try to seed,

'Target class [Database\Seeders\NamedTableSeeder] does not exist.'

It says it is at line 875:

'framework\src\Illuminate\Container\Container.php:875' but I have not touched this file,

Is there something I have done obviously wrong?

Many thanks,

Hi there, Caitlin Scouler! Unfortunately, the "Faker" library has been retired by the original developer. I imagine that's the issue that you're running into. It will work with older versions of Laravel and the like, but not more recent versions. It is the library that is responsible for creating the fake data to be added to the database. You can check out this blog article.

Honestly, I would consider reverting back to version 6 of Laravel as it is the latest LTS version.

Hope this helps! :sparkles:

Found the solution. https://laravel.com/docs/6.x/seeding#running-seeders

Once you have written your seeder, you may need to regenerate Composer's autoloader using the dump-autoload command:

composer dump-autoload
