Recently we’ve been having trouble with new versions of bundler and rubygems on Travis. I’m still investigating the Automate failures.
We had problems a few days ago with rubygems 2.7.0 and bundler 1.16.0 and the error was that it couldn’t
So the hack we put in place to “fix” it was to
gem uninstall bundler 1.16.0 and
gem install bundler 1.15.4.
Then Travis updated the ruby 2.3.1 container to rubygems 2.7.1 and that failed to
gem uninstall bundler 1.16.0 because it’s part of rubygems and you can’t uninstall the default version.
So yesterday I removed the hack and it started working fine again.
Today Travis updated the ruby 2.3.1 image to use rubygems 2.7.2 and now automate fails again
so I have to dig into it more to find out what the real error is because all we get from automate is “Unknown RC from method”.
