Compiling error sequelize-typescript but works with nodemon-CodePudding

I created a simple application using Sequelize/typescript

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;
}

But when I execute this code with nodemon the script works and create the "User" table, but when I try to compile it using tsc it fails with this error :

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'.

This is my 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"
  }
}

and my tsconfig.json

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

If anyone have an idea I take it, I don't understand how my code can be executed by nodemon but not compiled by tsc.

CodePudding user response：

Not sure what's causing this (maybe your Typescript version is incompatible with this sequelize version?) Perhaps adding skipLibCheck: true (so node_modules is not type-checked) to compilerOptions in tsconfig.json gets rid of the problem?

CodePudding user response：

Upgrade to sequelize 6.7.0 resolve this error.
