Although it install jekyll I can't continue, because an error message appears.
This is what the terminal says:
$ gem install jekyll
Successfully installed jekyll-3.1.3
Parsing documentation for jekyll-3.1.3
Installing ri documentation for jekyll-3.1.3
Done installing documentation for jekyll
1 gem installed
But this error message appears:
Did you run the correct command to install the Jekyll gem?
Would be really great if someone could help me!
