我在Laravel 9的迁移中遇到了一些问题。在我运行了“php artisan migrate”命令后，每个表都创建了索引。所以除了foregin键以外，一切都很好。我不知道为什么，也许有人知道是什么原因导致了这个问题，或者有一个解决方案。谢谢大家！

我的迁移：

Schema::create('supplier_orders', function (Blueprint $table) {
    $table->increments('Id');
    $table->unsignedBigInteger('Warehouse', false)->nullable(false);
    $table->unsignedBigInteger('Supplier', false)->nullable(false);
    $table->dateTime('StartedAt')->nullable(false)->useCurrent();
    $table->dateTime('CompletedAt')->default(null);
    $table->string('PrimeVoucherNumber', 100)->nullable(false);
    $table->index(['CompletedAt', 'Warehouse', 'Supplier'], 'CompletedWarehouseSupplier');
});

Schema::create('supplier_order_details', function (Blueprint $table) {
    $table->increments('Id');
    $table->unsignedInteger('SupplierOrder', false)->nullable(false);
    $table->unsignedBigInteger('Employee', false)->nullable(false);
    $table->unsignedBigInteger('Product', false)->nullable(false);
    $table->unsignedDecimal('Quantity', 18, 4)->nullable(false);
    $table->index(['SupplierOrder', 'Employee', 'Product'], 'OrderEmployeeProduct')->unique();
    $table->index(['Product', 'SupplierOrder', 'Quantity'], 'ProductOrder');
    });

Schema::table('supplier_order_details', function (Blueprint $table) {
    $table->foreign('SupplierOrder', 'FK_SupplierOrderDetail_SupplierOrder')->references('Id')->on('supplier_orders')->onDelete('CASCADE')->onUpdate('NO ACTION');
});
