I am trying to copy an entire ruby installation So, say for e.g. I installed ruby under /usr/ruby e.g. cp -R /usr/ruby /usr1; rm -rf /usr/ruby I want to be able to copy it to some other directory say /usr1/ruby and run (Let us also imagine that /usr/ruby has been deleted). My use case is that of cloning a ruby repo across the network. So the user that clones the ruby installation cannot see the original installation under /usr/ruby So, I did the copy (clone) and it was unable to find things like fileutils initially. Then, I set the RUBYLIB and it again failed in yaml.rb saying ruby/lib/ruby/1.9.1/yaml.rb:9:in `require': no such file to load -- stringio (LoadError) What other variables do I have to set to make a copied/cloned ruby installation work?

> e.g. cp -R /usr/ruby /usr1; rm -rf /usr/ruby Unfortunately with linux installed ruby, some things (like the #! first line of installed binaries) are hard coded to the location of ruby when they were first installed. If that's not a hinderance, though, *maybe* you could get by with changing rbconfig.rb Maybe. On windows interestingly this isn't a problem--it can't run scripts anyway so it always (for better or worse) just runs the first ruby it finds in the path. So you can move your ruby dirs in windows all right. -=r

Ruby remembers a lot of things about how it was built and where it was installed: see $ ruby -rrbconfig -rpp -e 'pp Config::CONFIG' Have a look in your rbconfig.rb, which may be somewhere like /usr/lib/ruby/1.8/i486-linux/rbconfig.rb Many of the constants in this file are defined relative to where rbconfig.rb itself exists, so they will be OK, but others may not. Tools like rake use 'bindir' + 'ruby_install_name' to locate the ruby interpreter itself (to reinvoke it) It is almost certainly going to be safer to recompile ruby to install under /usr1/ruby, and then distribute that. Use: ./configure --prefix=/usr1/ruby
