Laravel 5.6: Specified key was too long error

Laravel 5.6: Specified key was too long error

在Laravel执行以下命令：

php artisan migrate

这是由于Laravel5.6设置了数据库默认编码，现在的编码默认为“utf8mb4”（支持emoji），

开始查看了官网是这么说的：

“applications and as long as you are running MySQL v5.7.7 and higher you do not need to do anything.”

如果MySQL版本大于5.7.7就可以了，发现不行……

还是报：

[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

所以还是按照Migrations的文档老老实实的修改吧：

打开 AppServiceProvider.php 文件写入如下：

use Illuminate\Support\Facades\Schema;

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

在重新执行

php artisan migrate

成功！！！
