Current behavior

NestJs config module is not compatible with Typescript 4.
When trying to import the ConfigModule, its not available in IDE quick assist. Forcefully trying to import ConfigModule from @nestjs/config gives an error - Cannot find module '@nestjs/config' or its corresponding type declarations

Expected behavior

ConfigModule should be available after installing @nestjs/config

Minimal reproduction of the problem with instructions

Installed typescript and nestjs cli
Initialise a project, and then install @nestjs/config.
Try to import ConfigModule in AppModule, and it throws an error.

I compared with one of my old projects, and rollbacked the Typescript version to 3, after which the error goes away.

What is the motivation / use case for changing the behavior?

Not as per expectations from the documentation.

Environment

Nest version: 7.5.1

 
For Tooling issues:
- Node version: 14.15.0  
- Platform:  Mac 

Others:

Typescript version: ^4.0.5
