Undefined method Illuminate\Foundation\Application::share() when upgrading to Laravel 5.4

@sickaustrian As of laravel 5.4 share has been removed. You will have to use the singleton instead.

See: https://github.com/laravel/framework/commit/1a1969b6e6f793c3b2a479362641487ee9cbf736

@usman Thank you for your quick reply. Where exactly do I have to update share to singleton then?

Could you show us your composer.json file?

@R314x3 sure!

I think it's a problem with the JWT Auth Package. There are some issues at github (https://github.com/tymondesigns/jwt-auth/issues).

Here with the same error message: https://github.com/tymondesigns/jwt-auth/issues/975

@ R3l4x3, I see thank you. I guess I wait until the issue is resolved on github then.

I faced the same issue today when try to upgrade to Laravel 5.4.

After see the error message, I check the storage/logs/{log-file-today}.log to know exactly what the package is incompatible with Laravel 5.4.

I had the same problem.. How to solve it.

Check old packages/classes from config/app.php - I removed the ones not ready to support Laravel 5.4 to make it works again.

public function register() { $this->app['datatables'] = $this->app->instance('foo', function ($app) { $request = $app->make('yajra\Datatables\Request'); return new Datatables($request); } ); }
