I'm getting this error after creating a fresh laravel project

[ludovicmeurot]

I have the exact same error with the same context.

While not ideal, you can work around the issue by running the internal PHP server directly while waiting for the fix: php -S localhost:8000 -t .\public\

Same here
windows 10 installing laravel using powershell
Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://php.new/install/windows'))

and then

laravel new example-app

Can anyone with Windows update .env with following changes and try again:

-PHP_CLI_SERVER_WORKERS=4
+PHP_CLI_SERVER_WORKERS=1

[Zeinot]

crynobone
oh WOW that did work

-PHP_CLI_SERVER_WORKERS=4
+PHP_CLI_SERVER_WORKERS=1

why does that cause an issue ?

@Zeinot Submitted and explained in PR #53178

thanks it works

[CodeWithPranta]

I solved it by changing code: vendor\laravel\framework\src\Illuminate\Foundation\Console\ServeCommand.php:368

   ```

// return Carbon::createFromFormat('D M d H:i:s Y', $matches[1]);

    if (isset($matches[1])) {
        return Carbon::createFromFormat('D M d H:i:s Y', $matches[1]);
    }

    // Handle the error or provide a default value
    return Carbon::now();

I got same error to when create new laravel project

[matrixcoding101]

i am also getting same error with fresh laravel install. when i changed .env PHP_CLI_SERVER_WORKERS value 4 to 1 then its works.
-PHP_CLI_SERVER_WORKERS=4
+PHP_CLI_SERVER_WORKERS=1

my question is why this error occurred while fresh laravel install?

[BrayamFlorez]

También recibo el mismo error con la nueva instalación de Laravel. Cuando cambié el valor 4 de PHP_CLI_SERVER_WORKERS en .env a 1, funcionó. -PHP_CLI_SERVER_WORKERS=4 +PHP_CLI_SERVER_WORKERS=1

Mi pregunta es ¿por qué se produjo este error durante la instalación nueva de Laravel?

pareciera ser problema de versiones, sin embargo al usar el truco lo que hacemos es bajar la cantidad de workers comprometiendo el rendimiento, es mucho mejor alternativa modificar el metodo getDateFromLine($line) en el archivo ServeCommand.php, al fina en el return reemplazalo por:

if (isset($matches[1])) {
return Carbon::createFromFormat('D M d H:i:s Y', $matches[1]);
}

// Handle the error or provide a default value
return Carbon::now();
