Unable to install node-red-admin

I am trying to npm install -g node-red-admin but getting many errors and warnings. I am trying to install so I can run node-red-admin hash-pw

Console log below:

It looks like you have missing prerequisites (i.e. python) ...

gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.

You'll need to either install python or set the PYTHON environment variable so that NPM can find it.

Here's a stack overflow article with good info: https://stackoverflow.com/questions/15126050/running-python-on-windows-for-node-js-dependencies

Thank you....I will have a look.
