gen package or gen help throws error

[ritwik2finda]

I am a newbie, please help. I just installed Node.js v6.9.1 on my windows machine

npm install --global generate and npm install --global generate-package were successful.

When I fire gen package or gen help it throws the following error:

C:\>gen help
[20:51:35] starting generate

path.js:7
    throw new TypeError('Path must be a string. Received ' + inspect(path));
