'npm run bootstrap' fails on Linux (Mint 18.3)

[ShawnTalbert]

I get the following when executing npm run bootstrap.

I suspect the issue is your scripts cal out /bin/sh but on Mint the default shell is dash and apparently this script isn't dash compatible.

When I forced this script to execute with bash it succeeded.

~/s/material-components-web-components $ npm run bootstrap

> material-components-web-components@ bootstrap /home/shawn/s/material-components-web-components
> npm install && ./scripts/bootstrap-unreleased.sh
