Hi I have got confused by ruby/gems etc as i seem to have some kind of path issues somehow. First issue is i seem to have 3 flavours of ruby installed ...
# ruby -v ruby 1.9.3p374 (2013-01-15) [i686-linux] # /opt/ruby-enterprise-1.8.7-2012.01/bin/ruby -v ruby 1.8.7 (2011-12-28 MBARI 8/0x8770 on patchlevel 357) [i686-linux], MBARI 0x8770, Ruby Enterprise Edition 2012.01 # /opt/ruby/bin/ruby -v ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-linux] # grep ruby /etc/httpd/conf/httpd.conf LoadModule passenger_module /opt/ruby/lib/ruby/gems/1.8/gems/passenger-3.0.11/ext/apache2/mod_passenger.so PassengerRoot /opt/ruby/lib/ruby/gems/1.8/gems/passenger-3.0.11 PassengerRuby /opt/ruby/bin/ruby So i guess i am using /opt/ruby/bin/ruby for live web site? So then when i try to do anything with the gem command it is not happy... # gem -v /usr/bin/ruby: No such file or directory -- '--prefix=/usr' (LoadError) # /opt/ruby-enterprise-1.8.7-2012.01/bin/gem -v 1.8.15 /opt/ruby/bin/gem -v /usr/bin/ruby: No such file or directory -- '--prefix=/usr' (LoadError) Im assuming that i need to be using "gem -v" which in turn is the same as "/opt/ruby/bin/gem -v"? But neither works. Any idea how to set a path or some such so i can use the gem commands? I have Googled a bit but havent found a good (understandable!) answer. Also how do i uninstall the unused ruby versions? Thanks in advance. John -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
