I installed ruby, rails, gem, rvm in ubuntu 11.10 and tried to update ruby from 1.8.7 to the recommended 1.9.2 and it fails. No matter what I do rails reports /usr/bin/ruby1.8: bad interpreter: ls -l /usr/bin/ruby* lrwxrwxrwx 1 root root 22 2011-11-24 14:02 /usr/bin/ruby -> /etc/alternatives/ruby -rwxr-xr-x 1 root root 5516 2011-07-28 07:24 /usr/bin/ruby1.9.1 ls -l /usr/bin/gem* lrwxrwxrwx 1 root root 21 2011-11-24 14:02 /usr/bin/gem -> /etc/alternatives/gem -rwxr-xr-x 1 root root 545 2011-05-17 06:47 /usr/bin/gem1.8 -rwxr-xr-x 1 root root 547 2011-07-28 06:10 /usr/bin/gem1.9.1 lrwxrwxrwx 1 root root 8 2011-04-11 03:45 /usr/bin/gemtopbm -> gemtopnm -rwxr-xr-x 1 root root 9572 2010-06-25 22:50 /usr/bin/gemtopnm Synaptic says that 1.9.1 is 1.9.2 and this is confusing because 1.9.1 has incompatibilities. I have tried erasing and deleting all instances of ruby, rails, rvm and reinstalling with apt-get, with rvm, etc but am so stuck. Googling has not helped, Ive been at it all day and no luck, how should this be solved please?
