laravel-admin php artisan admin:install报错问题解决办法
问题描述:根据laravel-admin官方文档安装步骤,执行:php artisan admin:install 安装时报错。
其实是数据库创建特殊字符过长问题,laravel 5.4 改变了默认的数据库字符集,现在utf8mb4包括存储emojis支持。如果你运行MySQL v5.7.7或者更高版本,则不需要做任何事情。
当你试着在一些MariaDB或者一些老版本的的MySQL上运行 migrations 命令时,你可能会碰到下面这个错误:
D:\wwwroot\www.test.com>php artisan admin:install
Migration table created successfully.
In Connection.php line 664:
SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 1000 bytes (S
QL: alter table `users` add unique `users_email_unique`(`email`))
In Connection.php line 458:
SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 1000 bytes
解决方案在app\Providers\AppServiceProvider.php添加默认值,需要删除数据库migrations、users表。重新执行:php artisan admin:install
<?php namespace App\Providers; use Illuminate\Support\ServiceProvider; use Illuminate\Support\Facades\Schema; //add fixed sql class AppServiceProvider extends ServiceProvider { /** * Bootstrap any application services. * * @return void */ public function boot() { Schema::defaultStringLength(191); //add fixed sql } /** * Register any application services. * * @return void */ public function register() { // } }
