I am trying to install jekyll on my Mac, I don’t know much about ruby ​​or setting up / debugging these messages.

I get the following when running "sudo gem install jekyll"

Building native extensions.  This could take a while...

Answer 1

use this command:

$ sudo xcode-select -r 

then

$ sudo gem install jekyll

Hope this helps you.
