Hi. I need more information about the problem. When did you get this error?

There was a problem in older version and it was fixed https://github.com/butschster/LaravelMetaTags/commit/b1228fef55227dc519fe8efb25cdef21358ac9bc

The problem caused only when console commands were run. Maybe do you have this code

public function register()
{
        // This condition will be removed
        if (!$this->app->runningInConsole() || $this->app->runningUnitTests()) {
            $this->registerPackageManager();
            $this->registerMeta();

            $this->packages();
        }
}

in the service provider App\Providers\MetaTagsServiceProvider.

The register method should look like over there https://github.com/butschster/LaravelMetaTags/blob/master/src/Providers/MetaTagsApplicationServiceProvider.php#L25

[xLuisCumbi]

There is no Register method in App\Providers\MetaTagsServiceProvider. This is the code in that class:

protected function packages()
    {
        // Create your own packages here
    }

    // if you don't want to change anything in this method just remove it
    protected function registerMeta(): void
    {
        $this->app->singleton(MetaInterface::class, function () {
            $meta = new Meta(
                $this->app[ManagerInterface::class],
                $this->app['config']
            );

            // It just an imagination, you can automatically
            // add favicon if it exists
            // if (file_exists(public_path('favicon.ico'))) {
            //    $meta->setFavicon('/favicon.ico');
            // }

            // This method gets default values from config and creates tags, includes default packages, e.t.c
            // If you don't want to use default values just remove it.
            $meta->initialize();

            return $meta;
        });
    }

And what about version? When did you get this error?

[xLuisCumbi]

I'll try to explain what's happening.

I followed the install instructions

1. Command: Composer require...
2. Command: meta-tags:install ...
3. The MetaTagsServiceProvider exists

And i created this class:

use Butschster\Head\MetaTags\MetaInterface;
use App\Repositories\BlogsRepository;

class BlogsController extends AppBaseController
{
    /** @var  BlogsRepository */
    private $blogsRepository;
    protected $meta;

    public function __construct(BlogsRepository $blogsRepo, MetaInterface $meta)
    {
        $this->meta = $meta;
        $this->blogsRepository = $blogsRepo;
    }
public function blogPosts()
    {
        $blogPosts = Blogs::where('status', '=', 'Active')->paginate(4);

        $data['blogPosts'] = $blogPosts;
        $this->meta

            // Will render "Home page - Default Title"
            ->prependTitle('Home page')

            // Will include next, prev, canonical links
            ->setPaginationLinks($data)

            // Will change default favicon
            ->setFavicon('/favicon-index.ico');
        return view('front.blog.blogPosts')->with($data);
    }

Now I'm getting this error:

Class Butschster\Head\MetaTags\MetaInterface does not exist

What I'm doing wrong? I really wants to use this library, but please help me. Let me know if you need more information. Thanks in advance

Will be awesome if you have a full example/tutorial.

[butschster]

There can be two reasons.

1. Problems in App\Providers\MetaTagsServiceProvider, but you don't have any.
2. This service provider was not add to the providers array in your app config/app.php

[sabbirahmed395]

@Luismij If your are in same situation, remove app/Providers/MetaTagsServiceProvider.php, App\Providers\MetaTagsServiceProvider::class, line from config/app.php and config/meta_tags.php and run composer remove butschster/meta-tags. Install again. After installation run php artisan optimize:clear. This procedure works for me.

@majorsabbir Thank you!!! I had the same issue after installing on Laravel 7. I followed your instructions and it fixed the error.

[xLuisCumbi]

Thank you I'll try it and let you know if works for me

[livevsonline]

@majorsabbir I still have this problem also tried uninstalling and all (found out App\Providers\MetaTagsServiceProvider::class) wasent added to my cofig/app.php

[sabbirahmed395]

@livevsonline make sure you uninstall LaravelMetaTags first. run php artisan config:clear, then follow the installation process again Laravel Meta Tags Installation. if it still doesn't work run php artisan optimize. Note: After running php artisan meta-tags:install command if you found there is no meta-tags.php in config folder, check your current user permission.
