Laravel 5.6: Specified key was too long error

Laravel 5.6: Specified key was too long error

在Laravel執行如下命令：

php artisan migrate

這是因爲Laravel5.6設置了數據庫默認編碼，如今的編碼默認爲「utf8mb4」（支持emoji），

 

開始查看了官網是這麼說的：

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

若是MySQL版本大於5.7.7就能夠了，發現不行……

仍是報：

[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

 

因此仍是按照Migrations的文檔老老實實的修改吧：

打開 AppServiceProvider.php 文件寫入以下：

use Illuminate\Support\Facades\Schema;

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

在從新執行

php artisan migrate

成功！！！
