Laravel 5.1 to 5.2 upgrade error

Question

When I try to update our existing project from Laravel 5.1 to Laravel 5.2 using the official guide, I get an error after composer update when the post update

php artisan clear-compiled

is run. Here is the error.

Class Illuminate\Foundation\Composer does not exist

Has anyone had a similar problem? When I run composer update with the no scripts flag it updates regularly so it's a problem on the clear-compiled.

Below are my Service Providers and my composer.json file.

When I run

grep -nH -d recurse 'Composer' bootstrap/ app/ config/

This is what is returned:

bootstrap/autoload.php:7:| Register The Composer Auto Loader bootstrap/autoload.php:10:| Composer provides a convenient, automatically generated class loader bootstrap/autoload.php:42:| when working locally. However we will need to load in the Composer

This is how the autoload.php file looks like:

    <?php

define('LARAVEL_START', microtime(true));

/*
|--------------------------------------------------------------------------
| Register The Composer Auto Loader
|--------------------------------------------------------------------------
|
| Composer provides a convenient, automatically generated class loader
| for our application. We just need to utilize it! We'll require it
| into the script here so that we do not have to worry about the
| loading of any our classes "manually". Feels great to relax.
|
*/

require __DIR__.'/../vendor/autoload.php';

/*
|--------------------------------------------------------------------------
| Include The Compiled Class File
|--------------------------------------------------------------------------
|
| To dramatically increase your application's performance, you may use a
| compiled class file which contains all of the classes commonly used
| by a request. The Artisan "optimize" is used to create this file.
|
*/

$compiledPath = __DIR__.'/cache/compiled.php';

if (file_exists($compiledPath)) {
    require $compiledPath;
}

/*
|--------------------------------------------------------------------------
| Register The Workbench Loaders
|--------------------------------------------------------------------------
|
| The Laravel workbench provides a convenient place to develop packages
| when working locally. However we will need to load in the Composer
| auto-load files for the packages so that these can be used here.
|
*/
if (is_dir($workbench = __DIR__.'/../workbench'))
{
    Xtwoend\Workbench\Starter::start($workbench);
}

Could it be something about the workbench?

Update: a really horrible fix of returning the Composer.php from 5.1 to vendor/laravel/framework/src/Illuminate/Foundation lets the app function normally but I really need a better solution, one which can be pushed onto production.

Answer 1

The error you get is all about the packages that you use. Since the Composer class' location is changed, it is failed to get located.

From the upgrade notes:

The Illuminate\Foundation\Support\Composer class has been moved to Illuminate\Support\Composer.

Wait for the pull requests to get accepted, for instance the laracasts/generators package, which is included within your composer.json file, is one of the packages that is not yet compatible with Laravel 5.2

https://github.com/laracasts/Laravel-5-Generators-Extended/issues/81

Thus, one of the most commonly used package where this error is occured is the cviebrock/eloquent-sluggable.

https://github.com/cviebrock/eloquent-sluggable/issues/214.

There is nothing you can but wait for the pull requests to get accepted or just edit the vendor files which is not that cool option to do.
