warnings after upgrading to ruby 2.2.0

Question

/gems/htmlentities-4.3.2/lib/htmlentities/mappings/expanded.rb:465: warning: duplicated key at line 466 ignored: "inodot"

/gems/ruby-2.2.0/gems/fog-core-1.25.0/lib/fog/core/collection.rb:144: warning: circular argument reference - filters

The obvious suspicion is that these gems don't like ruby 2.2.0, but things seem to be working

Should I fear future, imminent failures, or has these gems just haven't caught up yet?

Answer 1

Both problems were solved in newer versions of these gems.

If I am depending on gems like that, I usually wait a little bit before switching the project to the latest and greatest ruby in production. Gems need time to get compatible with all the changes.

Answer 2

I to have like this error when install redmine 3.2: /usr/lib/ruby/gems/2.3.0/gems/htmlentities-4.3.1/lib/htmlentities/mappings/expanded.rb:465: warning: key "inodot" is duplicated and overwritten on line 466

All is simple - just edit this file and remove duplicated line!)

But sometimes need just check your htmlentities version and remove not needed

gem list htmlentities
gem uninstall htmlentities -v '4.x.x'
