Cannot find module 'jquery'

Question

I am using this tutorial to try to load jquery into my SPF project. http://dev.office.com/sharepoint/docs/spfx/web-parts/basics/add-an-external-library

I followed strictly

tsd install jquery --save

Update the config.json in the config folder to load jQuery from CDN. Add an entry to the externals field:

"jquery": "https://code.jquery.com/jquery-3.1.0.min.js"

Import jQuery in your web part:

import * as $ from 'jquery';

However I keep getting this errors

Warning - tslint - src/webparts/helloWorld/HelloWorldWebPart.ts(12,13): error no-unused-variable: Unused import: '$'
Error - typescript - src/webparts/helloWorld/HelloWorldWebPart.ts(12,20): error TS2307: Cannot find module 'jquery'.
Error - 'typescript' sub task errored after 3.97 s 

Answer 1

Try using npm to install the typings:

npm install --save @types/jquery
