While trying to run Jekyll serve on one of my website folders, I get the following error
Dependency Error: Yikes! It looks like you don't have jekyll-sitemap
or one of its dependencies installed. In order to use Jekyll as
currently configured, you'll need to install this gem. The full error
message from Ruby is: 'cannot load such file -- jekyll-sitemap' If you
run into trouble, you can find helpful resources at

How do I install jekyll-sitemap?
