When installing Ruby version 2.1.3 with rvm, an “Empty path passed to certificates update” type error occurred.

% rvm install 2.1.3

Searching for binary rubies, this might take some time.

When trying to use Ruby 2.1.3, the message “dyld: Library not loaded: /usr/local/lib/libgmp.10.dylib” appears, indicating that libgmp cannot be loaded.

% rvm use 2.1.3

Using /Users/your_username/.rvm/gems/ruby-2.1.3
dyld: Library not loaded: /usr/local/lib/libgmp.10.dylib
  Referenced from: /Users/your_username/.rvm/rubies/ruby-2.1.3/bin/ruby
  Reason: Incompatible library version: ruby requires version 13.0.0 or later, but libgmp.10.dylib provides version 12.0.0

It seems this can be fixed by reinstalling with the disable-binary flag as follows.

% rvm reinstall 2.1.3 --disable-binary
