Python is required information is not in the README file.

I was confused by misleading information.

Please specify the README file.
The Python 2.7 installation is required.

This is a npm module dependencies.
The Microsoft .NET Framework 2.0 SDK required on Window 7 System

Hi Minias, where do you see the need of Python ?

[minias]

hi, maroramilli
In order to use the NPM module, it dependency NPM-GYP.
this modules required python 2.7 Only.

tested Windows 7 64 and 32 bit.

https://github.com/nodejs/node-gyp

On Unix:
python (v2.7 recommended, v3.x.x is not supported)
make
A proper C/C++ compiler toolchain, like GCC
On Mac OS X:
python (v2.7 recommended, v3.x.x is not supported) (already installed on Mac OS X)
Xcode
You also need to install the Command Line Tools via Xcode. You can find this under the menu Xcode -> Preferences -> Downloads
This step will install gcc and the related toolchain containing make
On Windows:

Option 1: Install all the required tools and configurations using Microsoft's windows-build-tools using npm install --global --production windows-build-tools from an elevated PowerShell or CMD.exe (run as Administrator).
Option 2: Install tools and configuration manually:

Visual C++ Build Environment:

Option 1: Install Visual C++ Build Tools using the Default Install option.

Option 2: Install Visual Studio 2015 (or modify an existing installation) and select Common Tools for Visual C++ during setup. This also works with the free Community and Express for Desktop editions.

💡 [Windows Vista / 7 only] requires .NET Framework 4.5.1
Install Python 2.7 (v3.x.x is not supported), and run npm config set python python2.7 (or see below for further instructions on specifying the proper Python version and path.)

Launch cmd, npm config set msvs_version 2015
If the above steps didn't work for you, please visit Microsoft's Node.js Guidelines for Windows for additional tips.

If you have multiple Python versions installed, you can identify which Python version node-gyp uses by setting the '--python' variable:

$ node-gyp --python /path/to/python2.7
