thinkerbot / gem_env.sh

Created November 8, 2010 18:28

Illustrates GEM_HOME vs GEM_PATH

	# Two ENV variables control the 'gem' command:
	#
	# GEM_HOME: the single path to a gem dir where gems are installed
	# GEM_PATH: a standard PATH to gem dirs where gems are found
	#
	# A gem directory is a directory that holds gems. The 'gem' command will lay
	# out and utilize the following structure:
	#
	# bin # installed bin scripts
	# cache # .gem files ex: cache/gem_name.gem

	8. any junk left below the Rails::Initializer.run call/block in environment.rb

rvm PATH bug

	I have observed a bug in PATH on 'rvm use' where an extra ' :' is added,
	preventing discovery of executables along that last path. Without the debug
	info the relevant commmands and output are:

	% echo $PATH
	/Users/Simon/.rvm/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/git/bin:/usr/local/instantclient-10.2
	% rvm use 1.8.6@chiangs --create
	Using /Users/Simon/.rvm/gems/ruby-1.8.6-p399 with gemset chiangs
	% echo $PATH
	/Users/Simon/.rvm/gems/ruby-1.8.6-p399@chiangs/bin:/Users/Simon/.rvm/gems/ruby-1.8.6-p399@global/bin:/Users/Simon/.rvm/rubies/ruby-1.8.6-p399/bin:/Users/Simon/.rvm/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/git/bin:/usr/local/instantclient-10.2 :
