SQLSTATE[42000]: Syntax error or access violation:

laravel報錯：Illuminate\Database\QueryException : SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 1000 bytes (SQL: alter tableblog_adminsadd uniqueblog_admins_email_unique(email))

解決方案：

在 app/Providers/AppServiceProvider 的 boot 方法內添加：Schema::defaultStringLength(191);

修改後代碼如下：

<?php

    namespace App\Providers;

    use Illuminate\Support\ServiceProvider;
    use Illuminate\Support\Facades\Schema;

    class AppServiceProvider extends ServiceProvider
    {
        /**
         * Register any application services.
         *
         * @return void
         */
        public function register()
        {
            //
        }

        /**
         * Bootstrap any application services.
         *
         * @return void
         */
        public function boot()
        {
            //
            Schema::defaultStringLength(191);
        }
    }
