Upgrading rails from 5.0.2 to 5.1.0

I was trying to upgrade my current rails 5.0.2 version to the latest rails 5.1.0 version by running bundle update rails after adding gem 'rails', '~> 5.1' on my Gemfile and I got this error message. 

Bundler could not find compatible versions for gem "activesupport":
  In Gemfile:
    rails (~> 5.1) was resolved to 5.1.0, which depends on
      activejob (= 5.1.0) was resolved to 5.1.0, which depends on

          activesupport (>= 4.2.0)

  activesupport (< 5.1, >= 3.0.0)

Deleting Gemfile.lock then running bundle worked for me

This sounds like you need to try and upgrade to a newer version of jbuilder. However, looking at RubyGems the current dependancies for Jbuilder still say:

activesupport < 5.1, >= 3.0.0

IF this is the case, JBuilder doesn't yet support the more recent Activesupport, now required by Rails 5.1 - so perhaps JBuilder isn't yet available in Rails 5.1.

If you need to get the newer Rails, then you should probably consider:

  • Checking to see if there is a roadmap in JBuilder for this.
  • Raising a JBuilder ticket requesting support for that later Rails version.

You could try an override - since it may potentially just work, and that <5.1 is just since it's not yet been tested with the more recent version - just be prepared for glitches if there are genuine compatibility issues. I'd definitely rerun the whole of your test suite after trying that.

The alternative is to wait a little bit - this is a very fresh release - give other packages a chance to catch up with it.
