PHP require Autoload

So, I have a good and stable Laravel project running and I went to add a new migration but I keep getting the following errors:

PHP Warning: require(...vendor/autoload.php): failed to open stream: No such file or directory...

If I run composer update then I get the following error:

Composer could not find a composer.json file in...

However I have a composer.json file in my directory ...

Anyone encountered this issue before?

What folder are you currently in? If you are in a subfolder it can give stange errors like this.

@resin I am in the root directory where there are folders such as public, vendor, routes, etc. So the composer.json file should be found

Try with below commands,

  composer dump-autoload

nothing happen the use below,

  php artisan optimize
  composer update

@geowrge yeah I assumed that tbh and because coincidentally I had Windows updates last Friday... Made sure that files are not set to Read-Only... will have to check again or copy the folder to another directory

Seems to be an issue when working on a folder which is in OneDrive...

Then better to remove vendor folder and try with new ,

 composer install

Basically whenever the vendor folder is missing we get this error:

PHP Warning: require(...vendor/autoload.php): failed to open stream: No such file or directory...

The solution is simple, Just run this command:

composer update --no-scripts 
composer update
  • composer update --no-scripts It will Skips execution of scripts defined in composer.json file.
  • composer update It will update your depencencies as they are specified in composer.json file.

With this command, you will re-create the vendor folder in your project

For this error:

Composer could not find a composer.json file in...

Solution: You are in the wrong directory. Go to your project directory and then run any of your commands in the command prompt

Thanks @UdhavSarvaiya This is an old post but I just got this error after creating a new Laravel project with php 8.4 and trying to run php artisan serve . So I went back to version 8.3 and ran your commands and now it works.

Hi! Maby your composer.json is corrupt ?

Try :

composer init

This will walk you through creating a new composer.json file. After this, running composer install will download the dependencies.

If everything is set up correctly, your project should recognize the new migration after resolving these issues.

@birdietorerik you will not recover a project this way.

If composer.json is indeed damaged, running init will not create a file that works for laravel

Its a four year old question. Why do you need to chip in with bad advice?
