Always when I run brew update the Ignoring bigdecimal-1.3.2 because its extensions are not built. Try: gem pristine bigdecimal --version 1.3.2 warning shows up:

> brew update
Ignoring bigdecimal-1.3.2 because its extensions are not built.  Try: gem pristine bigdecimal --version 1.3.2
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 using Homebrew v1.7.7 (Homebrew/homebrew-core (git revision 77cae; last commit 2018-10-19), Homebrew/homebrew-cask (git revision c95843; last commit 2018-10-19)) and rbenv v1.1.1.

I already did gem pristine bigdecimal --version 1.3.2 and it says:

> gem pristine bigdecimal --version 1.3.2
ERROR:  While executing gem ... (Gem::Exception)
    Failed to find gems ["bigdecimal"] = 1.3.2

Even gem pristine --all doesn't fixed it.

The gem environment is showing me 2 gem paths. Is that fine?

  • Have you tried to uninstall it first? – Casper Oct 19 '18 at 15:35
  • @Casper Yes, I tried to uninstall the gem. `gem uninstall bigdecimal --version 1.3.2`: "_ERROR: While executing gem ... (Gem::InstallError) gem "bigdecimal" is not installed_" – ricardopereira Oct 19 '18 at 18:12
  • What about using `gem uninstall bigdecimal --all --force`? – Casper Oct 19 '18 at 19:42
  • You can also try `locate bigdecimal-1.3.4` to see where it is installed. Then move the folder and/or gemspec somewhere else for backup, then reinstall. – Casper Oct 19 '18 at 19:47
  • I run the `gem uninstall bigdecimal --all --force` and it successfully uninstalled `bigdecimal-1.3.5` but the issue persists. – ricardopereira Oct 20 '18 at 12:18
  • I search for "bigdecimal*" folders and it found some old folders in `/Users/ricardo/.gem/ruby/2.3.0/gems/bigdecimal-1.3.2/ext/bigdecimal` and `/Users/ricardo/.gem/ruby/2.3.0/gems/bigdecimal-1.3.2/lib/bigdecimal`. I deleted them but the issue persists. – ricardopereira Oct 20 '18 at 12:19
  • Btw. isn't `brew` a Ruby program. Is this program using the system Ruby, instead of your rbenv Ruby. Then this bigdecimal issue is with the system Ruby and not with the rbenv Ruby. `head -1 $(which brew)` shows you which Ruby executable `brew` is running. – Casper Oct 20 '18 at 17:47
  • @Casper Yes, I thought it was Ruby program but it seems not. `head -1 $(which brew)` shows `#!/bin/bash`. – ricardopereira Oct 22 '18 at 08:28

Make sure you're using the right gem. The following fixed it for me: 

$ which ruby
/usr/local/bin/ruby
$ /usr/bin/gem uninstall bigdecimal --all --force

(edit: fixed "remove" to "uninstall")
