解决Laravel错误1071 Specified key was too long的多种方法

If you are using MariaDB or an older version of MySQL, you need to place this code in your AppServiceProvider.php:

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

Inside config/database.php, replace this line for mysql

'engine' => null', 

with

'engine' => 'InnoDB ROW_FORMAT=DYNAMIC', 

Instead of setting a limit on your string lenght.Change  database.php which is in config folder where it says

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

I changed these to

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