You need to install the serverless-offline plugin using npm in order to use sls offline command.

Just simply run:

npm i -g serverless-offline

to install globally on your device or

npm i serverless-offline --save-dev

to install it as a development dependency in the active project. and then add this configuration to your serverless template:

plugins:
  - serverless-offline
