fails on Windows due to process.env.HOME being undefined

[jamesmanning]

Currently running 'yo typings foo' on a Windows machine fails unless you specifically set the HOME environment variable

» yo typings npm-node-json-db
path.js:7
throw new TypeError('Path must be a string. Received ' + inspect(path));
^

Appears to be used in 2 places AFAICT

https://github.com/typings/generator-typings/blob/e412656ae9e847a6570564988c191d5a5d13bf26/generators/app/index.js#L19

AFAIK Node v4 is when the os.homedir() was added which you could use instead of you're already requiring (are you're ok requiring) v4 or later.

https://nodejs.org/api/os.html#os_os_homedir

Otherwise, you can use the os-homedir npm module as a polyfill, or even just use a simple function to check for win32 like in this SO answer

function getUserHome() {
  return process.env[(process.platform == 'win32') ? 'USERPROFILE' : 'HOME'];
}

Thanks for the excellent report! Will fix it this afternoon

I have released 1.0.1 for this. Please see if it solves the problem.

I'm in the process of setting up appveyor, hopefully will avoid windows platform issue in the future. :)
