Install Instructions for Windows?

[johndeyrup]

Install instructions don't work on a windows machine.

I am trying to install it now under Windows 7. I am stuck at the "npm install":

C:\Users\delfinog\jupyter-nodejs>npm install

> zmq@2.15.3 install C:\Users\delfinog\jupyter-nodejs\node_modules\zmq
> node-gyp rebuild

So it says that it "Can't find Python executable". But it is exactly there where it is looking for it. Defining a PYTHON environment variable as suggested does not help.

Unable to install on Windows10 either (running the install from a Cygwin shell).

I don't get any Python error as @gdelfino but I get similar OS warnings (presumably not a problem as it says this is an optional dependency) and the "node-gyp rebuild" errors.

It's not at all clear to me from this output where the problem is.

I'm running into the same problem and haven't been able to fix it. I do think I've isolated the source though: installing zmq via npm on windows.

If I'm right, npm install zmq should fail for both of you, with a similar error message to the one you're getting now.

Wish I had more to contribute...

WOW this was frustrating.

First off, @mjbright - downgrade to node v8.11.3 then npm install --global --production windows-build-tools <==this step must be from admin console then npm config set msvs_version <2015|2017|whatever-version-of-visual-studio-you-use> then finally, npm install
