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

我正在学习本教程：

有人知道如何解决这个错误吗？

【问题讨论】：

您使用的是什么版本的软件包？好像是类型问题

标签： typescript nestjs

【解决方案1】：

我刚看到这个问题，和他们发布的最后一个版本的sequalize有关。

试用版本：

"sequelize": "6.6.2"

【讨论】：

降级到6.6.2 解决了我的问题。 6.6.4 版本似乎有问题。
为什么我降级了，但错误仍然出现，对吧？
它对我不起作用，但我忘记删除升级包 ^6.6.2 => 6.6.2 的插入符号，然后它起作用了，谢谢。
@HatemSat 谢谢，删除标记“^”原来是一个区别，现在它正在工作
您知道是否存在未解决的问题吗？几个月过去了，这还没有解决...

【解决方案2】：

目前所有高于6.6.2 的版本都不能正常工作。

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

如果它没有帮助检查您自己模型中类 Model 的扩展。

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

改为：

@Table
export class User extends Model
