我在laravel项目中使用xampp作为服务器。在创建迁移时,我遇到了一个错误:只能创建一个迁移表。其他人没有被创建。
这是错误:
**Migration table created successfully.
Migrating: 2014_10_12_000000_create_users_table
Illuminate\Database\QueryException : SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length
is 767 bytes (SQL: alter table `users` add unique `users_email_unique`(`email`))
at C:\xampp\htdocs\lsapp\vendor\laravel\framework\src\Illuminate\Database\Connection.php:664

您可以尝试以下方法:
AppServiceProvider.php
use Illuminate\Support\Facades\Schema; //Import Schema
function boot()
{
Schema::defaultStringLength(191);
}
希望有帮助。

如下所示更新config文件夹中的database.php文件
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
到
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
,它应该可以工作。如果不起作用,请如下所示在app / Providers /中更新AppServiceProvider.php。
use Illuminate\Support\Facades\Schema; //Import Schema
function boot()
{
Schema::defaultStringLength(191); //Solved by increasing StringLength
}
