在nestjs中序列化和typescript集成时出错

Question

我正在尝试使用typescript部署带有sequelize的nestJs。

我正在学习本教程：

有人知道如何修复这个错误吗？

Answer 1

我刚刚看到了这个问题，它与他们发布的sequalize的上一个版本有关。

请尝试以下版本：

"sequelize": "6.6.2"

Answer 2

目前，所有高于6.6.2的版本都无法正常工作。

尝试将package.json文件中的版本更改为"sequelize": "6.6.2"

如果它不能帮助您在自己的模型中检查class model中的扩展。

@Table
export class User extends Model<User, IUser>

更改为：

@Table
export class User extends Model
