I'm stuck and looking for help.
I'm not sure where the problem actually is but I hope to find the answer. 🙂
Problem details
I've installed '@types/lodash' using following command:
npm install --save-dev @types/lodash
And imported lodash in my .ts file using:
import * as _ from '@types/lodash';
When I run webpack I get following error:
ERROR in ./app/scripts/Components/GameBoard.ts
Module not found: Error: Cannot resolve module '@types/lodash' in /Users/mjelaska/Documents/DevProjects/connect-four/src/app/scripts/Components
@ ./app/scripts/Components/GameBoard.ts 3:8-32
Then I tried to get more details with
webpack --display-error-details
and got ⇣

Installing lodash to dependencies instead of devDependencies doesn't help:
npm install --save @types/lodash

You need the actual lodash
package (which contains the JS code that is lodash) and you also need the @types/lodash
package, which provides type definitions for the lodash
package (essentially, it tells TypeScript what's in the lodash
package).
So, you want to run both of these commands to get those two packages:
npm install --save-dev @types/lodash
npm install --save lodash
Then in your code, you import it as such:
import * as _ from 'lodash';
_.zip(array1, array1); // or whatever
