If I do a gem install with no sudo I get a permission denied…

If I do a sudo gem install I get “sudo: gem: command not found”

Im running Ubuntu feidty fawn with the rminstall stack

Any ideas?

Cheers  
Giorgio

why does it work without sudo then…  
I get all the messages …

Bulk updating Gem source index for: [http://gems.rubyforge.org](http://gems.rubyforge.org)  
ERROR: While executing gem … (Errno::EACCES)  
Permission denied - /opt/rminstall/ruby/lib/ruby/gems/1.8/cache/  
BlueCloth-1.0.0.gem

seems to be working but not enough permission…

any ideas?

yeah, probably is a path problem, clean up all the versions of gem (form  
/usr and /opt) and the re install ruby gems
