I'm running Ubuntu 10.04 and originally installed ruby 1.9.1 (from source). I've just decided to try out ruby 1.9.2 and rails 3, and it seemed like a good time to use rvm to deal with the multiple ruby installs and gemsets.
rvm installed and seems to be working, I installed ruby 1.9.2 in rvm and made that my default ruby. However, every time I try to install a gem under ruby 1.9.2 I see this error.
mark@Steve-Austins-Penguin:~$ gem install haml
ERROR: While executing gem ... (Errno::EACCES)

But if the correct installation, ruby and gem paths are showing here why is ruby trying to install gems to /home/mark/.gem
? All the variables and paths shown by env
look right, and I can't find a .gemrc
file anywhere on my system that might contain conflicting path settings.
So I guess my question is what might be causing rubygems to attempt to install to /home/mark/.gems
instead of the correct paths set by rvm?
