cyclotron-svc> npm install fails. Can't find Python executable.

[omkarkhair]

I'm installing cyclotron on Windows, and it seems there is a dependency on Python for the 'dtrace-provider' module.

C:\git\cyclotron\cyclotron-svc>npm install

> dtrace-provider@0.2.8 install C:\git\cyclotron\cyclotron-svc\node_modules\dtrace-provider
> node-gyp rebuild

C:\git\cyclotron\cyclotron-svc\node_modules\dtrace-provider>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 )

Update: I installed Python 2.7 with python in PATH and the npm install worked. There is a dependency on Python on the Windows platform.

Thanks for the update @omkarkhair. I'll get this added to the installation docs.

Running the following command from the node-gyp documentation resolves this on Windows:

npm install --global --production windows-build-tools

Looks like it installs Python 2.7 and Visual Studio Build Tools.

Great. Thanks :)

Just to be clear it would be nice to have the documentation on the project website remain inline with the project Readme. http://www.cyclotron.io/gettingstarted.html

Updated!
