PJO:~ PJO$ jekyll doctor
-bash: jekyll: command not found
PJO:~ PJO$

I updated to the latest Jekyll (or) if on GitHub Pages to the latest github-pages

• I ran jekyll doctor to check my configuration

Thanks DirtyF,

I am sorry that I did not see your response 10 hours ago. Anyway, I have learned much from searching the web. #6800 was very instructive.

I am new at ruby, etc. and seeking help. Please look at #6893. I am close to establishing a site but need some direction.

Thanks
Paul
