Laravel 5.4 把默认数据库字符集更改成 utf8mb4，作为对存储 emojis 的支持。只要你运行的是 MySQL v5.7.7 及更高版本，那么你就不会出现本文提到的错误。

对于那些运行 MariaDB 或旧版本的 MySQL 的程序，可能会在尝试运行迁移时遇到下面的错误：

[Illuminate\Database\QueryException]
SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes (SQL: alter table 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
如 Laravel 5.4 中关于 迁移 的文档，你要做的是编辑 AppServiceProvider.php 文件，并在 boot 方法内设置默认字符串的长度：

代碼: 選擇全部

use Illuminate\Support\Facades\Schema;

public function boot()
{
    Schema::defaultStringLength(191);
}

然后，就没然后了。

Stay Hungry, Stay Foolish.
