typescript - Modul hittades inte: Fel: Kan inte lösa modulen '@types/lodash'

Jag sitter fast och letar efter hjälp.

Jag är inte säker på var problemet faktiskt är, men jag hoppas hitta svaret. 🙂

Problemdetaljer

Jag har installerat '@types/lodash' med följande kommando:

npm install --save-dev @types/lodash

Och importerade lodash i min .ts-fil med:

import * as _ from '@types/lodash';

När jag kör webpack får jag följande fel:

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

Sedan försökte jag få fler detaljer med

webpack --display-error-details

och fick ⇣

⬆️ Uppdatering #1

Att installera lodash i dependencies istället för devDependencies hjälper inte:

npm install --save @types/lodash

Svar #1

Du behöver det faktiska lodash-paketet (som innehåller JS-koden som är lodash) och du behöver också @types/lodash-paketet, som tillhandahåller typdefinitioner för lodash-paketet (i princip talar det om för TypeScript vad som finns i lodash-paketet).

Så, du vill köra båda dessa kommandon för att få de två paketen:

npm install --save-dev @types/lodash
npm install --save lodash

Sedan importerar du det i din kod på följande sätt:

import * as _ from 'lodash';

_.zip(array1, array1); // or whatever
