so that means that it actually is an issue related to homebrew and cannot be resolved by some other measure other than an update for homebrew, right?

try xcode-select --install in Terminal.

This worked for me: Open Xcode, go to Preferences, go to Locations, update the Command Line Tools in the drop down to Xcode 10.0.

I solved the problem by identifying the gem command actually used by brew, which is (for me, with mojave just installed) under /usr/bin/gem. Use this absolute path sudo /usr/bin/gem pristine bigdecimal --version 1.3.3 sudo /usr/bin/gem pristine bigdecimal --version 1.3.4

and everything’s fine now. Hope it helps

Workaround solution for me ( I had ruby 2.5.1 installed by brew due to vim dependency)

uninstalled vim, ruby and restarted terminal (so now system ruby is active, v 2.3.7)
installed bigdecimal: sudo gem install bigdecimal
reinstalled vim (and with it ruby 2.5.1 as dep)

The solution from @ndreca is also working for me:

First uninstall ‘rbenv’ with dep on ‘ruby-build’
Then run sudo gem install bigdecimal

Restored bigdecimal-1.3.4

Reinstall ‘rbenv’ and restart terminal, I can brew without warnings 😃

this is a problem with the portable version of ruby that comes with Homebrew, if I use the version of ruby that I have installed on my mac I can install bigdecimal:

$ gem install bigdecimal

$ brew update

Ignoring bigdecimal-1.3.2 because its extensions are not built.  Try: gem pristine bigdecimal --version 1.3.2
Already up-to-date.

I’m also getting this on a secondary install (like not on my main Mac) and have not yet found a solution that worked.
