Looks like you need to change server.ts with:

import { NestFactory } from '@nestjs/core';
import { ApplicationModule } from './modules/app.module';

const app = NestFactory.create(ApplicationModule);
app.then(instance => instance.listen(3000, () => console.log('Application is listening on port 3000')));

I fixed the problem with app.then, but then I found this issue, and it looks similar to the problem I'm facing https://github.com/Microsoft/TypeScript/issues/16772

@felquis try yarn upgrade ts-node @types/node. Doing this solved it for me.

[jfmlima]

@felquis Doing this fixed my issues: npm install --save @types/node@latest ts-node@latest --force

[julianmnst]

Just tried @Jflima92 's solution with no success. Got this error instead:

Any ideas? Where's @kamilmysliwiec ? I'm really excited about Nest.

Hey guys, You can also try this and give me your feedback starter kit implementation with sequelize and jwt

[julianmnst]

Ok I reinstalled the project, had the first problem and then did npm install --save @types/node@latest ts-node@latest without --force. Then I checked my package.json and saw that one package (don't remember wich) still had the * on it's version. npm suggested a version, I manually wrote it on package.json, npm install again and that solved it.

[Itrulia]

fixing ts-node@2.1.0 and typescript@2.2.1 fixes it for me.

[kamilmysliwiec]

Hi, Fixed.

Do not forget to import the decorator ;)

import {Headers} from '@nestjs/common';
