Issue Installing on Windows

[michaelraypace]

Over the past two day's I've had issues installing on multiple platforms. Here are the errors I"m seeing on Windows:

{lamb} if not defined npm_config_node_gyp (node "C:\Program Files\nodejs\node_modules\npm\bin\node-gyp-bin\\..\..\node_modules\node-gyp\bin\node-gyp.js" rebuild )  else (node "" rebuild )

I have faced this same issue but it get solved by following this steps by modifying package.json

We don't have node-gyp in our package.json.

If you have a working fix please submit a PR. I don't have access to a Windows machine for testing.

All the links with how to use this at Windows are broken. Are there some work link? Pls

this help`s in most cases
npm install --global --production windows-build-tools

@oshape wow, that actually worked on Windows Server 2012, lol. I just knew it wouldn't, but I was wrong! This is regarding xml2json package that depends on this anyway. I had to have an admin prompt for both installing the build tools, then installing the local package xml2json as well.

For the person who said the link someone posted was broken, I think this link works

I have solved this. If you notice this part of the command else (node "" rebuild ) what I think is happening is that it is incorrectly evaluating if not defined npm_config_node_gyp as false and trying to run nothing instead of node-gyp. What you need to do is define your npm_config_node_gyp variable. You can do this like so:
export npm_config_node_gyp=<PATH_TO_NODE_GYP_PACKAGE_FOLDER> remember that Windows will need double backslashes. For me, it looked like this:
export npm_config_node_gyp=C:\\Users\\781990\\AppData\\Roaming\\nvm\\v6.11.0\\node_modules\\node-gyp

this help`s in most cases
npm install --global --production windows-build-tools

This works wonderfully. Though it took >30 mins to install..

@UncleGus export isn't recognized in windows powershell. Were you on mac/linux?
