Blade compiler exception after upgrade to v5.8

[mnlm]

• Lumen Version: v5.8.1
• PHP Version: 7.2.15

Description:

After upgrading from v5.7 to v5.8 I get the following error: ReflectionException: Class blade.compiler does not exist in ../vendor/illuminate/container/Container.php:794.

This is caused by calling the Blade::directive() function as shown below.

<?php

namespace App\Providers;

use Illuminate\Support\Facades\Blade;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Perform post-registration booting of services.
     *
     * @return void
     */
    public function boot()
    {
        Blade::directive('test', function ($expression) {
            return "<?php echo 'test'; ?>";
        });
    }
}

The Blade facade doesn't comes out of the box with Lumen. You'll need to specifically set its alias in your bootstrap file:

$app->alias('blade.compiler', Illuminate\View\Compilers\BladeCompiler::class);

That should theoretically work.

Thanks for your reply. I set the alias as suggested but the error remains.

// bootstrap/app.php
$app->withFacades();
$app->alias('blade.compiler', Illuminate\View\Compilers\BladeCompiler::class);

Something must have changed since v5.7. The Blade facade worked fine then, just had to uncomment $app->withFacades(); in the bootstrap file.

This is the PR that changed the way it was resolved was this one: laravel/framework#25497

You did register the ViewServiceProvider manually didn't you? https://github.com/laravel/lumen/blob/38b12bccff7ba009bbc931ac0c5dc5e1d09a98a2/bootstrap/app.php#L82

I didn't, but adding it doesn't change anything. Still the same error.

// bootstrap/app.php
$app->register(App\Providers\AppServiceProvider::class);
$app->register(App\Providers\AuthServiceProvider::class);
$app->register(Illuminate\View\ViewServiceProvider::class);

I can't really help you anymore at this point. Lumen doesn't work with views out of the box so I don't know for sure what's needed to make it work. I suggest you try one of the following support channels:

• Laracasts Forums
• Laravel.io Forums
• StackOverflow
• Discord
• Larachat
• IRC

I meant Blade*

Ok, I will keep looking into it. Thanks for your time.

I'm not using facades, but it might help you: I trigger the initialization of the 'view' instance in my AppServiceProvider::boot() method to make sure everything is bootstrapped.

Something like:

<?php

class AppServiceProvider extends ServiceProvider
{
    public function boot()
    {
        app('view');
        app('blade.compiler')->directive('my_directive', function ($expression) {
            return 'my_directive output';
         });
    }
   // ...
