Npm ERR! Cannot find module './install.js'

My project config.yml uses orb serverless: circleci/serverless-framework@1.0.1
When trying to do sls plugin installation, it gives problem related to node dependencies - where’s that coming from. My project is a python based project. The plugin install command run is -
sls plugin install -n serverless-python-requirements
The error is -
npm ERR! Cannot find module ‘./install.js’
