Tips on resolving handlebars 'module not found' error in typescript while compiling to umd

In my client-side JavaScript library written in TypeScript, I am attempting to incorporate Handlebars. However, when I try to import using

import * as Handlebars from 'handlebars'
, I encounter an error message stating that TypeScript "cannot find module typescript".

Switching to

import * as Handlebars from 'handlebars/runtime'
instead of just 'handlebars' did not resolve the issue for me.

After researching and coming across a similar problem discussed here, I attempted adding the Handlebars substitution to my tsconfig file without success in resolving the module finding issue.

I feel it is crucial to mention that I am utilizing umd compilation. While commonjs compilation works fine with the reference, I understand that commonjs is typically recommended for Node.js applications. Since I am developing a client-side library, this solution does not seem suitable. Targeting umd offers both commonjs and amd compilation options, which I believed would be ideal.

tsconfig:

{
  "compilerOptions": {
    "target": "es5",
    "module": "umd",
    "strict": true,
    // "paths": {
    //   "handlebars": ["handlebars/dist/handlebars.min.js"]
    // },
    "esModuleInterop": true   
  }
}

package json:

{
  "name": "test",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "handlebars": "^4.1.2"
  }
}

main.ts:

import * as Handlebars from 'handlebars'

export function hello() {
    Handlebars.compile("");
}

The desired outcome is to successfully integrate Handlebars into my library.
