Could not find a declaration file using Typescript with Yarn

[RaviRamDhali]

Typescript with Yarn
I am trying to install and use npm install fs-imagesize --legacy-peer-deps

Importing the following:

import Markdown from "react-markdown";
import remarkGfm from "remark-gfm";
import imageSize from "fs-imagesize";

Getting the following error:

Could not find a declaration file for module 'fs-imagesize'. 'c:/Projects/WebApp/ClientApp/node_modules/fs-imagesize/index.js' implicitly has an 'any' type.

Confirmed the following:
C:\Projects\WebApp\ClientApp\node_modules\fs-imagesize folder and files exists.
