Installing Ruby Despite Errors
In order to run Jekyll Now locally, so I can see changes before they are committed and published publicly, I’ve needed to get Ruby installed. However each attempt produced this error
ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions for the /Library/Ruby/Gems/2.3.0 directory.
The automated script can be run multiple times. In fact you should regularly run it to keep the components up to date. Thank you Moncef.
