Gatsby default starter - node.js

Question

This error came when I created gatsby-default-starter site. How to solve it. What is the problem with it?
Error message:

It seems that you are using Windows as OS. This issue is usually related to some additional dependencies that you may need. Try the following:
Delete your project (to avoid potentially corrupted dependencies).
Install the windows-build-tools by:
npm install --global windows-build-tools --vs2015
Run your starter command and develop it. For example:
npm install -g gatsby-cli
gatsby new gatsby-site
cd gatsby-site
gatsby develop
If the issue persists try installing manually the missing dependencies by:
npm install imagemin-pngquant#5.0.1 --save
npm install pngquant-bin#3.1.1 --save
For further details check Gatsby on Windows docs.
