The default source is https://rubygems.org, but you may have other sources configured. This guide will help you update your sources or configure yourself to use your own gem server. Without any arguments the sources lists your currently configured sources: $ gem sources *** CURRENT SOURCES *** https://rubygems.org This may list multiple sources or non-rubygems sources. You probably configured them before or have an old `~/.gemrc`. If you have sources you do not recognize you should remove them. RubyGems has been configured to serve gems via the following URLs through its history: * http://gems.rubyforge.org (RubyGems 1.3.6 and earlier) * http://rubygems.org (RubyGems 1.3.7 through 1.8.25) * https://rubygems.org (RubyGems 2.0.1 and newer) Since all of these sources point to the same set of gems you only need one of them in your list. https://rubygems.org is recommended as it brings the protections of an SSL connection to gem downloads. To add a source use the --add argument: $ gem sources --add https://rubygems.org https://rubygems.org added to sources RubyGems will check to see if gems can be installed from the source given before it is added. To remove a source use the --remove argument: $ gem sources --remove http://rubygems.org http://rubygems.org removed from sources EOF end def list # :nodoc: say "*** CURRENT SOURCES ***" say Gem.sources.each do |src| say src end end def list? # :nodoc: !(options[:add] || options[:clear_all] || options[:remove] || options[:update]) end def execute clear_all if options[:clear_all] source_uri = options[:add] add_source source_uri if source_uri source_uri = options[:remove] remove_source source_uri if source_uri update if options[:update] list if list? end def remove_source(source_uri) # :nodoc: unless Gem.sources.include? source_uri say "source #{source_uri} not present in cache" else Gem.sources.delete source_uri Gem.configuration.write say "#{source_uri} removed from sources" end end def update # :nodoc: Gem.sources.each_source do |src| src.load_specs :released src.load_specs :latest end say "source cache successfully updated" end def remove_cache_file(desc, path) # :nodoc: FileUtils.rm_rf path if not File.exist?(path) say "*** Removed #{desc} source cache ***" elsif not File.writable?(path) say "*** Unable to remove #{desc} source cache (write protected) ***" else say "*** Unable to remove #{desc} source cache ***" end end end
