[gentoo-user] Ruby problems

[Peter Humphrey]

Hello list,

Has anyone here succeeded in building a new system since the recent Ruby 
language upgrade? I keep being thwarted by failure such as this typical one:

>>> Install dev-ruby/rake-13.0.3-r1 into /var/tmp/portage/dev-ruby/
rake-13.0.3-r1/image
 * Running install phase for ruby26 ...
 * Running install phase for ruby27 ...
Traceback (most recent call last):
        3: from <internal:gem_prelude>:1:in `<internal:gem_prelude>'
        2: from <internal:gem_prelude>:1:in `require'
        1: from /usr/lib64/ruby/2.7.0/rubygems.rb:16:in `<top (required)>'
/usr/lib64/ruby/2.7.0/rubygems.rb:16:in `require': cannot load such file -- 
rubygems/compatibility (LoadError)
 * ERROR: dev-ruby/rake-13.0.3-r1::gentoo failed (install phase):
 *   Unable to generate gemspec file.

Similar failures occur whatever profile I use (of the suitable ones), and no 
matter whether I set amd64 or ~amd64 in make.conf.

It's possible that I had some unhelpful USE flags set, I suppose, but I did try 
to minimise them.

In the end I went back to a month-old backup and updated that instead.

Regards,
Peter.

That looks like you need to select the new ruby version with eselect.
It doesn't figure out the right version automatically, like python.

I tried setting ruby_targets_ruby30 in package.use (and ruby26 and 27 at 
different times). I also tried with no ruby targets specified. Shouldn't that 
have been enough?

Thanks. It's a pity that such important advice is hidden so effectively.
