Installation on mac

[fabbiocrux]

@ines .. thanks for sharing the frameworK... I think it absolutely wonderful..
To be honest, I am really novice in gatsby and Node.js programming.. I just trying to follow your instructions on you web and
I'm having a hard time, try to using using the template...
Initially I could run the app.. but I don't know what I have done wrongly after having an actualization of Mac and I can not anymore. I see the plugins are the problem.. but I don't have any clue how can I solve it.
(I erase and re-install my Command Line Tool).

Thanks for the help if it's possible
I really appreciate !
Thanks :)
