Hi ! I’m doing a new installation of rails , but i get a big problem with rubygem : [root@compute test\_projet\_rails]# ruby script/console Rails requires RubyGems \>= 0.9.4. Please install RubyGems and try again: [http://rubygems.rubyforge.org](http://rubygems.rubyforge.org) [root@compute test\_projet\_rails]# gem -v 1.2.0 [root@compute test\_projet\_rails]# irb irb(main):001:0\> require ‘rubygems’ LoadError: no such file to load – rubygems from (irb):1:in `require’ from (irb):1 irb(main):002:0\> What’s wrong with my configuration ? Thanks ! ---

Maybe you have two Ruby installations. The one that is started by “ruby” and “irb” doesn’t have a gem installation. The one that the “gem” command uses, does. Compare the output of: ``` $ cat `which gem` | head -n 1 $ ls -l `which ruby` ``` Stefan ---

thanks to take all this time to help me… this is better, after i removed the compiled version i get that : [root@compute src]# cat `which gem` | head -n 1 #!/usr/bin/ruby [root@compute src]# ls -l `which ruby` -rwxr-xr-x 1 root root 3748 jui 1 10:33 /usr/bin/ruby great ! but i when i try to run ruby that’s a drama… [root@compute src]# ruby -bash: /usr/local/bin/ruby: No such file or directory My path is : /usr/lib/ccache:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin maybe another thing to do for updating the path ? ---

Yes, bash caches the ruby → /usr/local/bin/ruby association. Here’s a description: [http://blog.byohosting.com/2008/01/17/how-to-clear-shell-command-path-cache/](http://blog.byohosting.com/2008/01/17/how-to-clear-shell-command-path-cache/) If everything else fails, open a new shell.

It seems that you have one ruby that was installed by your package manager (the /usr/bin/ruby one) and one manual installation. It is not a good idea to remove the one installed by the package manager because other packages might depend on it. You can remove the manual installation by deleting ruby, ri, rdoc, erb and testrb from /usr/local/bin and deleting everything with ruby in its name from /usr/local/lib. OTOH, having two ruby installations is not a problem at all. Just keep in mind that /usr/local comes first in your path. If you want to use that, get & install the rubygems package from rubyforge. That installs a gem command in /usr/local which again should shadow the /usr/bin one. Stefan ---
