Fatal error: Uncaught ReflectionException: Class config does not exist

Question

I'm working on an e-commerce project on Laravel 5.8, but since I accidently ran "laravel new" command on the project's folder I get this error when I'm trying to launch the project on a local server:

Fatal error: Uncaught ReflectionException: Class config does not exist in C:\wamp64\www\e-commerce\vendor\laravel\framework\src\Illuminate\Container\Container.php:788 Stack trace: 0 C:\wamp64\www\e-commerce\vendor\laravel\framework\src\Illuminate\Container\Container.php(788): ReflectionClass->__construct('config') 1 C:\wamp64\www\e-commerce\vendor\laravel\framework\src\Illuminate\Container\Container.php(667): Illuminate\Container\Container->build('config') 2 C:\wamp64\www\e-commerce\vendor\laravel\framework\src\Illuminate\Container\Container.php(615): Illuminate\Container\Container->resolve('config', Array) 3 C:\wamp64\www\e-commerce\vendor\laravel\framework\src\Illuminate\Foundation\Application.php(767): Illuminate\Container\Container->make('config', Array) 4 C:\wamp64\www\e-commerce\vendor\laravel\framework\src\Illuminate\Container\Container.php(1227): Illuminate\Foundation\Application->make('config') 5 C:\wamp64\www\e-commerce\vendor\laravel\framework\src\Illuminate\Log\LogManager.php(417): Illuminate\Container\C in C:\wamp64\www\e-commerce\vendor\laravel\framework\src\Illuminate\Container\Container.php on line 788"

The error on line 788 refers to that portion of code:

$reflector = new ReflectionClass($concrete)

This happened after I cloned my repo from Github. Now for every project that I try to run on a local server I get this error.

I tried "composer install", "composer update", "composer dump-autoload" but they all give the same error with this line at the end: "Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 255".

I checked the .env file to see if there was a namespace issue too, but there's none of it.

Thank you in advance for your help.

Was the repo up to date before you naffed your project folder? – Powel

Modify your composer.json to remove any artisan script call out of the scripts section. Then try again. – Pitt

composer update --no-scripts and then try composer update – Sprout

RiggsFolly actually no, it wasn't. – Gitt

composer update --no-scripts did the trick on my end, thanks @DilipHirapara – Fernyak

Answer 1

Try to remove de files in:

cd bootstrap/cache/
rm -rf *.php

In this directory are the file that initializes the structure, cache directory that contains structure-generated files for performance optimization, such as files and route cache services.

I tried all of the methods above but none of them worked. Can anyone provide me something else? – Gitt

after deleting the files in boostrap/cache/.. i did composer dump-autoload.. and it worked for me – Delao

Answer 2

You may check the following items

1. Check whether your APP_NAME has space. If space is there, use it in quotes.
2. run

rm -r /bootstrap/cache

to Delete everything from bootstrap/cache/ folder.

3. run

composer dump-autoload

Hope it will work

Answer 3

I tried @gulCunha 's answer and it worked.

After that, you have to run composer update in order to create a new composer.lock and php artisan config:cache after that and you should be good to go.

I was creating a new Laravel 9 project with composer and got the same error.

Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 255

But this time it was not about the cache. Regardless of what the errors suggest, the problem was actually caused by the following lines found in vendor/vlucas/phpdotenv/src/Util/Str.php

$converted = $encoding === null ?                                             
    @\mb_convert_encoding($input, 'UTF-8') :                                  
    @\mb_convert_encoding($input, 'UTF-8', $encoding);

It actually occurred as I didn't have Multibyte String enabled when I built my PHP binaries. After rebuilding PHP with --enable-mbstring, the problem went away.

You should run the composer update command, and then php artisan optimize to clear the config cache and routes.

Answer 7

Make sure your .env file is the exact same as in your local environment. Make sure that the values on your .env file don't have spaces. Those that have spaces should be wrapped in quotes

Answer 8

I had a similar problem. Here is how I fixed it.

It started when I installed Toastr in my config/app.php providers. I had failed to add the trailing ",". Hence the problem.

Solution: Check the last package you installed. Check if you have added it correctly in the service providers.

If you are getting this error when migrating a Lumen 5.8 web application to Laravel 5.8, when running php vendor/bin/phpunit, check if main Test\TestCase has use CreatesApplication; inside the class body, and not it's own function createApplication().

abstract class QdtTestCase extends BaseTestCase
{
    use CreatesApplication;

    /**
//     * Creates the application.
//     *
//     * @return Application
//     */
//    public function createApplication()
//    {
//        return require __DIR__ . '/../bootstrap/app.php';
//    }
}

You can copy this Test\CreatesApplication .php file from a fresh Laravel 5.8 project.

Alternatively, you could write:

abstract class QdtTestCase extends BaseTestCase
{
    // use CreatesApplication;

    /**
     * Creates the application.
     *
     * @return Application
     */
    public function createApplication()
    {
        $app = require __DIR__ . '/../bootstrap/app.php';

        $app->make(Kernel::class)->bootstrap();

        return $app;
    }
}

The "ReflectionException: Class config does not exist" error occurs isnside \Illuminate\Foundation\Testing\RefreshDatabase::usingInMemoryDatabase when calling config('database.default') or in \Illuminate\Foundation\Testing\Concerns\MakesHttpRequests::prepareUrlForRequest, when calling config('app.url').

I tried all the answers here and none of them worked for me. I tried composer diagnose and that is how I discovered that I was not running the latest stable version of composer. I then run composer self-update and that finally solved my issue.
