Difficulty using TensorFlow and MediaPipe with TypeScript in browser

I’m trying to get face detection working in the browser on a local web server (not Node.JS).

import ‘@tensorflow-models/face-detection’ results in this error:

localhost/:1 Uncaught TypeError: Failed to resolve module specifier “@tensorflow-models/face-detection”. Relative references must start with either “/”, “./”, or “…/”.

import “https://cdn.jsdelivr.net/npm/@tensorflow-models/face-detection

does not give a compiler error, but if I add
import * as faceDetection from ‘@tensorflow-models/face-detection’;

it fails to compile.

index.html contains:

There is a problem with the JS face detection MP/TF module. Face mesh works
