Laravel 迁移错误:语法错误或访问冲突:1071 指定的键太长;最大密钥长度为 767 字节
问题描述
使用 php artisan make:auth
[Illuminate\Database\QueryException] SQLSTATE[42000]:语法错误或访问冲突:1071 指定的键太长;最大密钥长度为 767 字节(SQL:alter table users add unique users_email_unique(email))
[PDOException] SQLSTATE[42000]: 语法错误或访问冲突:1071 指定的键太长;最大密钥长度为 767 字节
根据 官方 Laravel 7.x 文档,你可以很容易地解决这个问题.
更新您的 /app/Providers/AppServiceProvider.php 以包含:
使用 Illuminate\Support\Facades\Schema;/*** 引导任何应用程序服务.** @return 无效*/公共函数引导(){架构::默认字符串长度(191);}<块引用>
或者,您可以为您的数据库启用 innodb_large_prefix 选项.有关如何正确启用此选项的说明,请参阅您的数据库文档.

According to the official Laravel 7.x documentation, you can solve this quite easily.
Update your /app/Providers/AppServiceProvider.php to contain:
use Illuminate\Support\Facades\Schema;
/**
 * Bootstrap any application services.
 *
 * @return void
 */
public function boot()
{
    Schema::defaultStringLength(191);
}
Alternatively, you may enable the
innodb_large_prefixoption for your database. Refer to your database's documentation for instructions on how to properly enable this option.
