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
如果您运行“php artisan migrate”时出现此错误。你可以这样修改你想要更新的表:
DB::statement('ALTER TABLE table_name ROW_FORMAT = DYNAMIC;');
在迁移脚本中。例子:
class MyMigration extends Migration {
/**
* Run the migrations.
*/
public function up()
{
DB::statement('ALTER TABLE table_name ROW_FORMAT = DYNAMIC;');
Schema::table('table_name', function ($table) {
//....
});
}
/**
* Undo the migrations.
*/
public function down()
{
//....
}
}
然后再次运行php artisan migrate
我得到了这个错误尽管我已经有了(实际上因为我已经有了)
模式:defaultStringLength (191);在AppServiceProvider.php文件中。
原因是我试图在我的一个迁移中设置一个高于191的字符串值:
Schema::create('order_items', function (Blueprint $table) {
$table->primary(['order_id', 'product_id', 'attributes']);
$table->unsignedBigInteger('order_id');
$table->unsignedBigInteger('product_id');
$table->string('attributes', 1000); // This line right here
$table->timestamps();
});
删除1000或将其设置为191解决了我的问题。
