Laravel whoops and class str not found

Question

I have tried to update my Laravel from 5.4 to 5.5 but I am having some errors-

Uncaught Error: Call to undefined method Whoops\Handler\PrettyPageHandler::setApplicationPaths() in...

Laravel log shows something like this-

production.ERROR: Class 'str' not found {"exception":"[object] (Symfony\Component\Debug\Exception\FatalThrowableError(code: 0): Class 'str' not found at C:\xampp\htdocs\teste\config\cache.php:91) [stacktrace]

production.ERROR: Class 'str' not found {"exception":"[object] (Symfony\Component\Debug\Exception\FatalThrowableError(code: 0): Class 'str' not found at C:\xampp\htdocs\teste\config\cache.php:91) [stacktrace]

This is how my cache.php looks-

'prefix' => env(
    'CACHE_PREFIX',
    str::slug(env('APP_NAME', 'laravel'), '_').'_cache'
 ),

The line 91 is the str::slug. Any idea what am I missing?

Did you follow the official upgrade guide? laravel.com/docs/5.5/upgrade#upgrade-5.5.0 — dparoli

You need to change your string function call like one of these-

str_slug('your_string');

Or this

use Str;

Str::slug('your_string');

Make sure to run this once you make changes in your config files so your config changes can be cached again and work as intended-

php artisan config:cache

To use Str in blade templates you can add to app.php

class_alias('Illuminate\Support\Str', 'Str');

or for newer versions to alias section in config/app.php

'Str' => Illuminate\Support\Str::class,

and {{ Str::slug('your_string') }} becomes available/
