Error while installing gatsby.js starter templates - node.js

Question

I want to make web app using gatsby.js
I have installed gatsby-cli globally using npm install.
But whenever I run gatsby new gatsby-starter-forty https://github.com/codebushi/gatsby-starter-forty or any other starter template command. I always end up with following error in my terminal
C:\Users\Sachin Verma\Desktop\gatsby>gatsby new gatsby-starter-forty https://github.com/codebushi/gatsby-starter-forty

Please suggest some way to fix it. As I am new to Node.js and can't fully understand the error

Judging by your console output, I can see that you're using Windows. You will need some additional setup in order to get a working environment.
Take a look at the official Gatsby on Windows docs.
In a nutshell, Gatsby recommends installing the windows-build-tools package to run on Windows:
The recommended way to setup your build environment on Windows is to install the windows-build-tools package by running npm install --global windows-build-tools --vs2015
If this doesn't work for you, there is further information (including troubleshooting) in the official Gatsby on Windows docs.
Alternatively, if you're on Windows 10, a good solution is to use Gatsby in the Windows Subsystem for Linux (WSL). To set it up, follow the instructions on the WSL Linux docs.
