编译错误 sequelize-typescript 但适用于 nodemon

Question

我使用 Sequelize/typescript 创建了一个简单的应用程序

src/index.ts

import { Sequelize } from "sequelize-typescript"


const sequelize = new Sequelize({
    database: 'typescript',
    dialect: 'mysql',
    username: 'root',
    password: 'root',
    host: "localhost",
    models: [__dirname + '/**/*.model.ts'],
})

sequelize.sync({ force: true }).then(() => console.log("Database connected!"))

src/models/user.model.ts

import { Table, Column, Model } from 'sequelize-typescript';

@Table
export default class User extends Model {
    @Column
    name!: string;
}

但是当我使用 nodemon 执行此代码时，脚本可以工作并创建“用户”表，但是当我尝试使用 tsc 编译它时，它会失败并出现以下错误：

node_modules/sequelize-typescript/dist/model/model/model.d.ts:10:31 - error TS2417: Class static side 'typeof import("/home/maxou/Documents/Learn-Typescript/Back/node_modules/sequelize-typescript/dist/model/model/model").Model' incorrectly extends base class static side 'typeof import("/home/maxou/Documents/Learn-Typescript/Back/node_modules/sequelize/types/lib/model").Model'.

12     model<TCreationAttributes, TModelAttributes>(model: string | ModelType<TCreationAttributes, TModelAttributes>): ModelCtor;

这是我的 package.json

{
  "dependencies": {
    "mysql2": "^2.3.0",
    "nodemon": "^2.0.13",
    "sequelize": "^6.6.5",
    "sequelize-typescript": "^2.1.0",
    "ts-node": "^10.2.1",
    "typescript": "^4.4.3"
  },
  "scripts": {
    "dev": "nodemon src/index.ts",
    "build": "tsc"
  }
}

还有我的 tsconfig.json

{
    "compilerOptions": {
        "module": "CommonJS",
        "target": "ES6",
        "experimentalDecorators": true,
        "emitDecoratorMetadata": true,
        "outDir": "dist",
        "strict": true
    },
    "include": [
        "src/**/*"
    ]
}

如果有人知道我接受它，我不明白我的代码如何由 nodemon 执行但不能由 tsc 编译。

Answer 1

不确定是什么原因造成的（也许您的 Typescript 版本与此 sequelize 版本不兼容？）也许在 tsconfig.json 中添加 skipLibCheck: true（所以 node_modules 未经过类型检查）到 compilerOptions 摆脱问题？

Answer 2

升级到 sequelize 6.7.0 解决这个错误。
