Postinstall script installation fails when installing locally

This is a Bug Report

Description

I know a correct way to install globally using npm install serverless - g, but when installing locally in own project with npm install serverless --save, an error occurs during execution of postinstall.js.

Is this bug? or does it mean sls has not supported for installing locally?

step to reproduce

• Create directory with mkdir sls-project && cd sls-project
• Run npm init
• Run npm install serverless --save, and you will see the following error

$npm install serverless --save

npm install -g serverless/serverless should work for now for anyone else looking.

as a quick fix you can use npm install --legacy-bundling in your project dir. This will make sure that npm disables the optimization and flattening. But remove the node_modules dir before.
