Hi!

I'm currently trying to work my way through the Trailhead "Get Started with Hybrid Development", but am having problems when I attempt to "forcedroid create".

When it gets to "Installing "cordova-plugin-whitelist" for android" it fails with:
 

Failed to install 'cordova-plugin-whitelist':TypeError: Path must be a string. Received undefined
at assertPath (path.js:7:11)

Failed to restore plugin "cordova-plugin-whitelist" from config.xml. You might need to try adding it again. Error: TypeError: Path must be a string. Received undefined

This error is not imediately fatal, but after a time I see:

forcedroid create failed

Command failed: cordova plugin add https://github.com/forcedotcom/SalesforceMobileSDK-CordovaPlugin#v5.0.0 --force

Whereas, this last bit is fatal.

FWIW,

Any ideas what is wrong or how to fix this?
