Ruby cannot load such file - active_support/core_ext/object/blank

Question

I was trying to run brew doctor but system popped up error of

/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- active_support/core_ext/object/blank (LoadError)

Searched online and another post suggested to just "gem install activesupport" but then I ran into error of:

ERROR:  Error installing activesupport:
    i18n requires Ruby version >= 2.3.0.

I also tried to rvm install ruby-2.3.0 but the same error popped again

Try `brew tap --repair` and make sure `brew doctor` looks reasonable.

Running brew style fixed this issue for me.

Update

As mentioned in the comments, for some people the solution is:

brew update-reset

@BigHeadCreations , @Mave: I was able to confirm that this happened directly after a brew cleanup. Just prior to this, brew update said gave updated commit: 6db1c7383. brew update-reset fixed the issue.

I face the 'sunspot_rails-2.1.0' issue while upgrade the ruby version ruby 2.2 to ruby 2.5 for rails 4.2 and here I would like to share with you which has worked for me.

"LoadError: no such file to load -- active_support/core_ext/object/to_json"

In my case, I have to force homebrew/linuxbrew to use its own portable-ruby to fix it.

I am running ArchLinux with ruby 2.7.0 installed, after I switch to homebrew's portable-ruby by export HOMEBREW_FORCE_VENDOR_RUBY=1 as described in the manpage and issue brew update, homebrew automatically downloads portable-ruby 2.6.3, and everything's back to normal.

I think the root cause might be homebrew's incompatible with a higher version of ruby.
