'gem update --system' is causing build to abort

This line in my appveyor install section is now breaking the build. It was working fine 2 weeks ago. I've not changed anything related to appveyor.

    Perhaps a bug with Ruby Gems:


    Odd that this broken version slipped into AppVeyor images.

    So, as I understand during Ruby upgrade we happened to install "broken" Ruby Gems?

    We are running these lines during Ruby installation:

    gem install rubygems-update --no-ri --no-rdoc
    gem update --system

    Looks like re-installing Ruby should fix the issue?

    Is this something you want me to add to my install section? Or just some notes?

    I'm not sure if that helps. But perhaps re-installing Ruby during the build will? You can also remove gem update --system for now or switch to a "previous" build worker image.
