jekyll does not work in my windows 7

Question

I have installed jekyll in my windows 7, but it does not work. I have created a folder called jekyllSite and have included the necessary files in the folder, then I open Command Prompt and and cd in that folder and run jekyll code. It generates the following message. I can not understand what is wrong?

Answer 1

The output you've provided is just a description of what jekyll executables can do. To have any results you should use jekyll command either to build the site (to prepare static files instantly) or to host the site.

So, in those cases you just either use:

jekyll build

or

jekyll serve

respectively.
