In case you're coming from a google search, make sure that you have a .env file in which APP_ENV is set to local. (if you cloned a project from github, the first thing is to run cp .env.example .env. or in windows copy .env.example .env That was actually the problem in my case)

Then run composer install again.

Please check first artisan file present in root folder and this error is occurred because some file is missing from your project, download new laravel project and check all files with your existing project

If composer update and composer install not work then you can try this composer require laravel/sanctum

You could try

composer update

That worked for me when I had this same issue. In my case what made me discover this issue was when i tried to run the artisan command and it didn't return anything

So I tried composer dumpautoload which threw me this same error mentioned

composer update did the trick

In my case this error happened to me when i removed a package with composer remove, then i realized somehow, something affected my config files in config directory, and they all become empty.

Solution for me was simply getting those files from Laravel repository and copy them into config directory. (and of course in case you need to do vendor publish for specific libraries, you should do it again.)

in my case this was the error

> @php artisan package:discover --ansi

In AuthServiceProvider.php line 29:

  syntax error, unexpected '=>' (T_DOUBLE_ARROW), expecting ')'


Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 1

I solved it by upgrading PHP version to 7.4

because i was using Arrow functions in the AuthServiceProvider that came up in 7.4

Running the command php artisan package:discover --ansi by itself might tell you more about the issue. In my case correcting a character out of place in the .env solved it.

If none of the solutions work for you, the handling the post-autoload-dump event returned with error code 1 error can also be caused by using Composer 2 instead of Composer 1. That can happen when you run the install command manually in something like a Dockerfile, and it installs newest. Just modify your command to install the last 1.x.x stable version with the --1 option:

curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer --1

Or, specify a certain version with --version=x.x.x:

curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer --version=1.10.17

It might be good to also delete your vendor directory and composer.lock file so that nothing stale interferes with the version downgrade, before calling composer install as usual.

In my case, I had left over references to classes in a recently removed composer package. In your laravel app, check config/app.php, particularly the providers and aliases properties, for references to the class specified in the error.

In case the error appears when upgrading from Laravel 6 to Laravel 7, the command composer require laravel/ui "^2.0" solves the problem (see https://laravel.com/docs/7.x/upgrade#authentication -scaffolding)

I came across this when upgrading from 5.8 to 6.x.

I had str_slug() in config/cache.php and config/session.php.

I have changed it to Str::slug() and the error has disappeared.

See https://laravel.com/docs/6.x/upgrade#helpers.

You have added the service provider in config/app.php for the package that is not installed in the system.

You must have this line in your config/app.php. You can either remove it or install the package GeneaLabs\LaravelCaffeine\LaravelCaffeineServiceProvider

See https://github.com/GeneaLabs/laravel-caffeine.

Run the line below via CLI to install the package.

 composer require genealabs/laravel-caffeine

Add this in composer.json. Then dusk has to be installed explicitly in your project:

"extra": {
    "laravel": {
        "dont-discover": [
            "laravel/dusk"
        ]
    }
},

I found this solution here
