我的数据库中有一个名为 affilaite 的表。但是当我尝试创建一个名为 product 的新表时，它给了我一个错误 php artisan make:migration create_product_table

PHP Fatal error:  Cannot declare class CreateAffiliateTable, because the name is already in use in /home/manak/Desktop/manu/Edolve/database/migrations/2021_03_09_063908_create_affiliate_table.php on line 7

Answer 1

从这个错误我认为你已经有一个名为 DocumentsContract.BuildDocumentUriUsingTree 的迁移。

请更改您的迁移名称或删除旧迁移

Answer 2

检查您的数据库/迁移文件夹。如果文件已经存在，则将其删除。此外，如果已经有一个名称完全相同的表，则从数据库中删除该表。在数据库中还有一个迁移表。也从那里删除表名，然后再次尝试迁移。根据 Laravel 约定，迁移是复数，模型名称是单数。所以最好尝试 CreateAffiliatesTable 而不是 CreateAffiliateTable

Answer 3

使用此命令创建 $ php artisan make:migration create_products_table

php artisan make：迁移不创建新表
