RubyGems Metadata Issue

[benverseman]

• What were you trying to do?

  • Attempting to update from administrate 0.19.0 to greater version

• What did you end up with (logs, or, even better, example apps are great!)?
  bundle update administrate
  Fetching gem metadata from https://rubygems.org/........
  Resolving dependencies...
  Could not find compatible versions

Because administrate >= 0.20.0 depends on activerecord >= 6.0, < 8.0
and Gemfile depends on activerecord >= 8.0.0,
administrate >= 0.20.0 cannot be used.
So, because Gemfile depends on administrate ~> 0.20.1,
version solving has failed.

• What versions are you running?
  • Rails 8
  • administrate 0.19

Looks like the issue lies with the dependencies listed on Rubygems.org. When I manually add the repo from Github, bundler installs administrate just fine.

There's are a couple of things here, first is support for Rails 8 is merged, but not released yet: #2705.

I also saw an issue where you might end up with an older version (which amusingly it will work), but it's worth being mindful of: #2703 (comment)

You can work around this by bundling from main for now (or from the sha associated with the merged in Rails 8 support), but only if you're keen to be on the bleeding edge of the beta releases.

There will be a release soon, as everything for v1 is looking good to go.
