Answer 1

you just need one more step

go to app.php on bootstrap folder and uncomomment or modif this line

// $app->register(App\Providers\AppServiceProvider::class);

to this code

$app->register(App\Providers\AppServiceProvider::class);

have a good day

Answer 2

You need couple of things to do. I also faced this issue and fixed it by following these two steps

1. Go to app.php in bootstrap directory and uncomment or modify this line.

   // $app->register(App\Providers\AppServiceProvider::class);
   

2. Now you need to define boot()function in AppServiceProviderfile

       public function boot()
       {
          Schema::defaultStringLength(191);
       }
   

Then you are good to go!

Answer 3

Go to config in file database.php then edit

'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',

to

'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',

Answer 4

1. in bootstrap/app.php un-comment this line:

$app->register(App\Providers\AppServiceProvider::class);

2. in app/AppServiceProvider.php add below public function to AppServiceProvider class:

public function boot()
  {
    Schema::defaultStringLength(191);
  }

Answer 5

Known to work in Laravel/Lumen 7.x:

I've tried the un-commenting of AppServiceProvider::class and other solutions mentioned above, but the following worked for me.

If you look in /vendor/laravel/lumen-framework/config/database.php for charset and collation, the code checks your .env file and resorts to utf8mb4 and utf8mb4_unicode_ci, respectively.

If your database' charset is set to utf8 and collation to utf8_unicode_ci, simply add the following to your .env file:

# .env
...
DB_CHARSET=utf8
DB_COLLATION=utf8_unicode_ci
...

Answer 6

use Illuminate\Support\Facades\Schema; //AppServiceProvider.php

public function boot(){
Schema::defaultStringLength(191);
}

//rollback your migration or delete all table from database then migrate again.
