Activesupport error while installing rails in jruby
I installed jRuby using rvm. It's version is jruby-1.6.7.2 [ i386 ]. Now I am trying to install rails on top of it. But I am getting following error
ERROR: Error installing rails: activesupport requires Ruby version >= 1.9.3.
I am using following command to install rails which I found in many answers on so itself.
jruby -S gem install rails --pre --no-rdoc --no-ri
I also tried passing --1.9 option to jruby so that it can use ruby 1.9 interpreter. But that also not working.
jruby --1.9.3 -S gem install rails
My RVM list is as follows :
rvm rubies
=> jruby-1.6.7.2 [ i386 ]
ruby-1.8.7-p358 [ i686 ]
* ruby-1.9.3-p194 [ i686 ]
ruby-1.9.3-p286 [ i686 ]
Please guide me whats going wrong?
Are you able to update your JRuby version?
Alternatively, try set this shell variable:
export JRUBY_OPTS=--1.9
...then re-execute your gem install rails command.
