Issue #20870 has been updated by nobu (Nobuyoshi Nakada). Status changed from Open to Third Party's Issue Please ask the rubygems upstream. ---------------------------------------- Feature #20870: GEM_ROOT - https://bugs.ruby-lang.org/issues/20870#change-110424 * Author: dsisnero (Dominic Sisneros) * Status: Third Party's Issue ---------------------------------------- I know we can set GEM_HOME. If I have multiple rubies installed I would like GEM_HOME to be GEM_ROOT/#{RUBY_ENGINE}/#{RUBY_VERSION} without requiring an external script or wrappper script to run ruby and change environment variables -- https://bugs.ruby-lang.org/
