There is a discrepancy between my ruby version of RVM, and the actual version

  • 0

There is a discrepancy between my ruby version of RVM, and the actual version that my system seems to use.

Discrepancy:

max@max-VirtualBox:~/ruby/app$ ruby -v
ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-linux]
max@max-VirtualBox:~/ruby/app$ rvm list

rvm rubies

   ruby-1.9.3-p286 [ i686 ]
=* ruby-1.9.3-p327 [ i686 ]

So I tried,

max@max-VirtualBox:~/ruby/app$ rvm --default use 1.9.3

RVM is not a function, selecting rubies with 'rvm use ...' will not work.

and my rvm info lists ruby 1.9.3 as my default ruby version, and rvm has been updated. But my rails app still seems to be in ruby 1.8.7 syntax, as it says in ruby -v

How do I make it that my entire system is using the right ruby version?

I appreciate your help.

    Looks like RVM has not properly integrated into your shell

    a) try to reinstall it with curl -L https://get.rvm.io | bash -s stable --ruby

    b) (OR) try to manually add following lines to the end of your $HOME/.bashrc OR $HOME/.profile file

    export rvm_prefix=$HOME
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

    You’ll have to restart your shell to reload these vars
