NestJS env variable undefined

Question

I'm trying to set configuration variables on my project using the official documentation.

I added the following line to my app.module.ts imports:

ConfigModule.forRoot({
  isGlobal: true
}),

I created a .env file at the root of my project with the following content:

MY_VARIABLE=myself

And I use dependecy injection to get access to the configuration service:

constructor(private configService: ConfigService) {}

However the following line logs 'Env variable: undefined'

console.log('Env variable: ', this.configService.get<any>('MY_VARIABLE'));

Sounds like you've got it set up properly. Can you share a reproduction? In the snippets you've provided I can't see a problem. — Jay McDoniel, Apr 26 '20 at 16:08

Several scenarios:

You don't have .env file
.env is incorrectly defined
You're trying to access environmental variables from .env located outside the server's root path
You need to install dotenv package
Deploying to Serverless and in the functions (or other deployable folder) the .env is missing (even though it's in the root location it has to be there too)
