ERROR TS6054: File '~lib/#tensorflow/tfjs-node.ts' not found - tensorflow.js

Question

I'm trying to use AssemblyScript to build a WebAssembly inference engine for a TensorFlow.js model that I have.
I started with essentially the quickstart AssemblyScript app (which works great) and then simply added #tensorflow/tfjs to my dependencies:
$ npm install --save #tensorflow/tfjs
and added an import to assembly/index.ts:
import * as tf from "#tensorflow/tfjs";
Full code here on Github
This results in an error when I build it:
$ npm run asbuild
> test-assemblyscript#1.0.0 asbuild
> npm run asbuild:untouched && npm run asbuild:optimized
> test-assemblyscript#1.0.0 asbuild:untouched
> asc assembly/index.ts --target debug
ERROR TS6054: File '~lib/#tensorflow/tfjs.ts' not found.
import * as tf from "#tensorflow/tfjs";
~~~~~~~~~~~~~~~~~~
in assembly/index.ts(1,21)
FAILURE 1 parse error(s)
Am I misunderstanding the import syntax? I am puzzled why it would be looking in ~lib for this versus node_modules.

If you are sure the module you are trying to import is assemblyscript files, you can import with something like this ./node_modules/#tenderflow/tfjs.
I am not sure if #tensorflow has assembly files built, but I did that on assemblyscript-json for assemblyscript#0.19.8 (0.25.2 doesn't have that problem).
For example
assemblyscript-json has exported assemblyscript files from its package, so I can do this (ref)
import { JSON } from './node_modules/assemblyscript-json/assembly';
export function formatJsonString(jsonString: string): string {
const jsonObj: JSON.Obj = <JSON.Obj>JSON.parse(jsonString);
return jsonObj.stringify();
}
