I've been trying to run a script in the terminal and every time I do I get:

$ ruby directory.rb
dyld: Library not loaded: /usr/local/lib/libgmp.10.dylib
  Referenced from: /Users/claretrembath/.rvm/rubies/ruby-2.1.3/bin/ruby
  Reason: image not found
Trace/BPT trap: 5

I realized that when checking ruby -v I am given the same output:

$ ruby -v
dyld: Library not loaded: /usr/local/lib/libgmp.10.dylib
  Referenced from: /Users/claretrembath/.rvm/rubies/ruby-2.1.3/bin/ruby
  Reason: image not found
Trace/BPT trap: 5

Any ideas on how to resolve this?

  • It seems that when ruby is compiled, it will "opportunistically" link against gmp. This can be disabled with the configure script's --without-gmp option. In fact, this is what homebrew's ruby package does, as of Sep. 2019 (github.com/Homebrew/homebrew-core/pull/43841) Commented Feb 16, 2021 at 20:36

I just encountered similar issue and was able to resolve it following an answer from superuser.

brew update && brew install gmp && rvm reinstall 2.1.4

Seems this was an issue with libgmp.10.dylib.

Really the rvm reinstall isn't needed. At least in my case (same error message though).

For dyld: Library not loaded: /usr/local/lib/libgmp.10.dylib

you need brew update && brew install gmp

Seems like pretty poor form of the Ruby maintainers to require a third party math library and not mention it anywhere

I ended up solving this by including the brew's gmp directory when installing:

rvm install ruby-2.2.5 --with-opt-dir=$(brew --prefix gmp)

I've solved this issue by installing libyaml and gmp via Homebrew on a self hosted GitHub actions server without the need for rvm or ruby using this command brew install gmp && brew install libyaml to fix an error in ruby/setup-ruby:

 warning: It seems your ruby installation is missing psych (for YAML output).
...
 Library not loaded: '/usr/local/opt/libyaml/lib/libyaml-0.2.dylib' (LoadError)

I solved with:

brew install libyaml 
brew install libffi       
asdf plugin-update ruby    
asdf install ruby latest or version

Looks like it is an issue with upgrading the Ruby version.

Try:

$ brew rm cloog; brew install cloog

This seems much like this similar issue: "Upgrading to Ruby 2.1.3 on Mac OSx 10.9.5"

Hope that works for you.
