I’m setting Ruby to v 2.4.3 in .ruby-version but all Netlify builds are failing with jekyll-4.0.0 requires rubygems version >= 2.7.0, which is incompatible with the current version, 2.6.14
or maybe even your build image version (A more flexible build architecture with updated Linux) - not sure which you’re using but trusty is pretty old and xenial is what we hope you’ll use, and I know you’re a longtime customer
I’ve solved this problem. I am using an old Ubuntu version on my Netlify install, but that doesn’t make a difference. However, using Ruby 2.6.3 works, so I assume your Ruby version 2.4.3 comes with a too old version of rubygems for Jekyll 4.
Incidentally, your Ubuntu image comes with Ruby 2.6.2 pre-installed, so that’s probably a better choice to avoid installing 2.6.3 every build.
Thanks for the suggestion – I probably should have figured this out!
