I just set up Jekyll on my Linux machine and installed (I think) all the necessary dependencies. When I try to run jekyll serve or jekyll build, I get the error displayed below. However, if I run jekyll new "test" to create a new site, it works just fine.
Here is the error message I am receiving (it's the exact same for serve and build):

Any help would be greatly appreciated, I'm new to using Jekyll and Ruby.
Try to do a :
gem install jekyll-sitemap
