在Laravel 5.4上使用php artisan make:auth迁移错误
[Illuminate\Database\QueryException] SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes (SQL: alter tabl e users add unique users_email_unique(email)) [PDOException] SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes

为了避免更改代码中的任何内容，只需将MySQL服务器更新到至少5.7.7

其他回答
对于不想更改AppServiceProvider.php的人。 (在我看来，仅仅为了迁移而更改AppServiceProvider.php是一个坏主意)
您可以将数据长度添加回database/migrations/下的迁移文件，如下所示:
create_users_table.php
$table->string('name',64);
$table->string('email',128)->unique();
create_password_resets_table.php
$table->string('email',128)->index();
如前所述，我们在App/Providers中添加到AppServiceProvider.php
use Illuminate\Support\Facades\Schema; // add this
/**
* Bootstrap any application services.
*
* @return void
*/
public function boot()
{
Schema::defaultStringLength(191); // also this line
}
你可以在下面的链接中看到更多细节(搜索“索引长度& MySQL / MariaDB”) https://laravel.com/docs/5.5/migrations
BUT WELL THAT's not what I published all about! the thing is even when doing the above you will likely to get another error (that's when you run php artisan migrate command and because of the problem of the length, the operation will likely stuck in the middle. solution is below, and the user table is likely created without the rest or not totally correctly) we need to roll back. the default roll back will not work. because the operation of migration didn't like finish. you need to delete the new created tables in the database manually.
我们可以这样做使用修补器如下所示:
L:\todos> php artisan tinker
Psy Shell v0.8.15 (PHP 7.1.10 — cli) by Justin Hileman
>>> Schema::drop('users')
=> null
我自己有一个问题与用户表。
之后你就可以开始了
PHP artisan migrate:回滚

对我来说很有魅力!
将此添加到config/database.php
'engine' => 'InnoDB ROW_FORMAT=DYNAMIC',
而不是
'engine' => 'null',
最干净的解决方案是去你的数据库并更改:
default_storage_engine to InnoDB
你很可能有MyISAM。
如果你没有任何数据已经分配到你的数据库执行以下操作:
进入app/Providers/ appserviceprovider .php并添加
使用说明\ \ ServiceProvider的支持;
在方法boot()内部;
模式:defaultStringLength (191);
现在删除数据库中的记录，用户表中的ex。 运行以下命令
