Another Rubyzip problem

[DanRathbun]

@brewsky

I could directly include the rubyzip code in my own namespace, but using a gem seemed like the official way to do this. Like @DanRathbun mentioned here

For the record, that was an old post. Use of RubyGems (especially binary gems) has gotten progressively more complicated and problematic over the years.

So what used to work easily, does not anymore as Thomas explained in his linked post:

• Install Prawn gem in SketchUp 2016 - #2 by tt_su

Around SU v2018 RubyGems core changed and it’s web repository stopped working with older versions that SketchUp still had.

Re RubyZip, I believe is all pure Ruby. No binaries.

It has what it lists as minimum required Ruby version, but I think this may just be the “supported” minimum version. Ie, the author does not support installing the gem into old Ruby version that are at end of life.
