TS2585: 'Promise' only refers to a type, but is being used as a value here - node.js

Question

I'm getting the following error
node_modules/rxjs/internal/Observable.d.ts:82:59 - error TS2585: 'Promise' only refers to a type, but is being used as a value here. Do you need to change your target library? Try changing the lib compiler option to es2015 or later.
Formatted it looks like this,
node_modules/rxjs/internal/Observable.d.ts:82:59 - error TS2585: 'Promise' only refers to a type, but is being used as a value here. Do you need to change your target library? Try changing the `lib` compiler option to es2015 or later.
82 toPromise<T>(this: Observable<T>, PromiseCtor: typeof Promise): Promise<T>;
~~~~~~~
Found 1 error.
But the code I'm trying to run is right from the examples,
import { range } from 'rxjs';
import { map, filter } from 'rxjs/operators';
range(1, 200).pipe(
filter(x => x % 2 === 1),
map(x => x + x)
).subscribe(x => console.log(x));
I have in my tsconfig.json
"target": "ES2018",
"module": "es2015",
"lib": ["es2015"],
I'm running Rx.js 6.3.3, TypeScript 3.2.2 under Node v11.6.0. I've tried
npm i --save-dev #types/es6-promise
and just about every combination of changing lib and module
My ts config is exactly this,

Answer 1

Problem
TypeScript has two modes.
A project-builder mode (when tsc is invoked with no arguments)
A compile-mode (when tsc is invoked with any arguments) which does not read from the configuration file tsconfig.json
If that sounds confusing, it's even more confusing when you account for
the flag for the compiler-mode to accept a configuration file is called --project
inside the project-builder's configuration file there the pragma is called "compilerOptions"
the compiler-mode and the project-builder mode accept the same configuration file
Anyway, the problem here was that TypeScript was simply ignoring the configuration file in the current working directory that I was running it in.

Answer 2

Just install #types/node from npm. This should solve the problem.
npm install #types/node

Answer 3

In my case I simply added a tsconfig.json file with the following contents where the significant part relating to the above error is "target": "es2015":
{
"compilerOptions": {
"noImplicitAny": false,
"noEmitOnError": true,
"removeComments": false,
"sourceMap": true,
"target": "es2015"
},
"include": [
"file.ts"
],
"exclude": [
"node_modules",
"wwwroot"
]
}

Answer 4

I've found this solution that worked for me:
Check if the tsconfig.json file has build in Properties set to "Content" rather than "None", if not right click on the tsconfig file and set the build action to Content. After this reload the project, the error should go away

Answer 5

Use this while compiling.
tsc async_await.ts --lib es2015
