mac :( :( :(

[yall]

Good morning all.
I come back to you regarding my installation on mac ...
so I managed to compile perfectly hise with xcode 8 (my mac does not take xcode 10)
however, when exporting a UI plugin, I have the following problems.
impossible to install xcpretty and rubygem surely because of SSL.
from my mac terminal, i can't install xcpreety because it can't connect to rubygem. so i have the following error (Could not find a valid gem 'xcpretty' (> = 0), here is why:
Unable to download data from https://rubygems.org/ - SSL_connect returned = 1 errno = 0 state = SSLv2 / v3 read server hello A: tlsv1 alert protocol version (https://rubygems.org/latest_specs.4.8.gz) )
anyone have a solution to work around this problem?
I am completely lost, it's been 4 days that I am blocked and that I lose patience ^^
I tried with mac 10.9.5 then mac sierra, always the same problem. on the internet I looked for solutions regarding SSl but it totally exceeds me, I would like an ultra simplified explanation if possible.
thank you for your answers and sorry for my english written with google translation ...

I'm really trying hard to remember how I got around this problem

Have you tried installing Rubygems manually as instructed below?

Keep your head up mate... You'll get it sorted in the end
