Jekyll - command not found

Question

I am trying to get Jekyll running but I have no experience with Ruby.
As far as I can tell the installation of Jekyll has succeeded.
However:

$ jekyll
         


        

Answer 1

Here's an updated answer for 2020 (soon 2021). To install any Ruby gem, whether it's Jekyll, Bundler, Rails, etc., you need a proper Ruby development environment on a Mac. There are various ways to install Ruby on a Mac, as I have written about in great detail in my definitive guide to installing Ruby gems on a Mac. The only one I recommend is to use a Ruby manager because it's the most flexible and sets you up for success for the long term. My preferred one is chruby because it's the lightest and easiest to use. As part of installing Ruby, you also need to properly configure your shell startup file (typically ~/.zshrc or ~/.bash_profile) so that it knows where to find the gems you install. Otherwise, you'll get the "command not found" error, which I've also written about.

Since there are several steps involved in setting up a working Ruby development environment on a Mac, I wrote some scripts to automate the whole process and make things easier and faster for people. You can read more about the scripts in my guide mentioned above.
