Failed to install lwipfy

[slidenerd]

First of all, thank you for the awesome work on the library, i was trying to install it and got this issue

> lwip2@1.0.3 install D:\bots\qrbot\node_modules\lwip2
> node scripts/install.js

Installing lwip. If this fails, just install GraphicsMagick (http://www.graphicsmagick.org/).

I understand it needs some external dependency from this error but I am not sure how to go about that external dependency, any suggestions.

It says, if it fails install GraphicsMagick, does it want an exe file or npm module for graphics magick

Hmm, looks it doesn't find npm in the PATH. What do npm --version and node --version output?

[slidenerd]

npm --version = 3.10.8 and node --version = 6.9.1

The issue is how lwip2 tries to install the necessary package:
https://github.com/IonicaBizau/lwip2/blob/918c8817755f798287e38d47ba0f63c09a0f244f/lib/install.js#L15

On Windows this fails because npm needs to be invoked as npm.cmd.

[IonicaBizau]

Oh, didn't know about npm.cmd!

[IonicaBizau]

@reppners Can you do an npm install either in this repo or image-to-ascii to get the latest lwip2? Hopefully this works. I cannot test it right now.

[reppners]

works 👍
