queryString not working

The message I have while trying to import queryString is "Could not find a declaration file for module ‘query-string’ ".

I installed npm i query-string@6.1.0 and that didn’t work. Next I tried npm install @types/query-string and that didn’t work either.

Any suggestions???

Here’s my code:
import React from “react”;
import queryString from ‘query-string’;

const Posts = ({ match, location }) => {

const result = queryString.parse(location.search);


return (



  Year: { match.params.year } , Month: { match.params.month}




export default Posts;

I’m having this same issue. Does anyone know the solution?

This is from the Routing section, Video 10.

I got this working. I uninstalled query string and then reinstalled it without the version:

npm uninstall query-string
npm i query-string
