Sequelize-typescript: Property 'sync' does not exist on type 'Sequelize'

[sunzongzheng]

I got this:

model.ts like this:

Although I use ts-node to run it, it works well.

How to avoid this error message?

[sunzongzheng]

https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/sequelize works well

[serranoarevalo]

@sunzongzheng how did you fix this?

[sunzongzheng]

@serranoarevalo I use official sequelize width @types/sequelize in the end.

[RobinBuschmann]

@sunzongzheng sad to hear. Since you closed this issue I assumed you’ve get it working.

[RobinBuschmann]

@serranoarevalo can you provide your compiler options please or a lot easier to check for me: can you provide an example repo which reproduces the issue?

[serranoarevalo]

@RobinBuschmann Hi Robin, I also moved on from sequelize-typescript but I still remember the problem.

It was directly caused by by having "esModuleInterop": true on the tsconfig.json. After a while I discovered that skipLibCheck:true "fixed" the error on my console but it swallowed an import error, after inspecting a bit into the source code the SequelizeOrigin import wasn't working.

[serranoarevalo]

@sunzongzheng Thanks!

[RobinBuschmann]

@serranoarevalo Did it also say SequelizeOrigin is not a constructor function type?

[serranoarevalo]

@RobinBuschmann yes sir.

I have same error.
This issue seems to be linked to this issue
@types/sequelize Conflicting exports of Model #16588

[sagnol]

well... I don't know why it works. 😅
I edit tsconfig.json

    "esModuleInterop": false,
    "skipLibCheck": true

and I have no error anymore.

Same error here :(
Editing tsconfig.json didn't work either.
I'm using NestJs btw

@MauJovi Can you provide an example repo, which reproduces the issue?

[nikhilseepana]

import { Injectable } from '@nestjs/common';
import { Sequelize, Model } from 'sequelize-typescript';

@Injectable()
export class databaseProviders {
useFactory = async () => {
const sequelize = new Sequelize({
operatorsAliases: false,
dialect: 'postgres',
username: 'user',
host: 'hostname',
database: 'db',
password: 'pass',
port: 5433,
});
await sequelize.sync();
return sequelize;
}
}

This shows me the Error "Property 'sync' does not exist on type 'Sequelize'".

my tsconfig files is like below
{
"compilerOptions": {
"module": "commonjs",
"esModuleInterop": false,
"skipLibCheck":true,
"declaration": true,
"removeComments": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"target": "es6",
"sourceMap": true,
"outDir": "./dist",
"baseUrl": "./"
},
"exclude": ["node_modules"]
}

@nikhilseepana Can you provide a repository? I cannot reproduce it with the example you provided.
