I spent a good amount of time trying to get this to work a few days ago, but had issues with rvm. Thought this post might help, but in a fresh 10.10 install if rvm is used when trying gem install rails I get the following
: While executing gem ... (Errno::EACCES) Permission denied
It shouldn't be denied though since it's in the home directory. The only way I could get an up to date ruby and rails installed was by removing rvm (rvm implode) and manually installing 1.9.2 and then following the update-alternatives instructions located here: http://ubuntuforums.org/showthread.php?p=10274200#post102742...
Is anybody else successfully accomplishing it the way this blog suggests? The internet is relatively sparse with up to date instructions for installing rails without problems on Ubuntu, it makes me miss the rolling release model of arch where everything just worked instantly.
