无法在RVM中更改默认的Ruby版本

Question

When I do ruby -v I get:

ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]

which ruby returns:

/usr/bin/ruby

rvm list returns:

rvm rubies
=* ruby-2.1.0 [ x86_64 ]
ruby-2.1.2 [ x86_64 ]
# => - current
# =* - current && default
#  * - default

When I change the current and default Ruby version to 2.1.0. then ruby -v returns:

ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-linux]

And which ruby shows:

/home/akhil/.rvm/rubies/ruby-2.1.0/bin/ruby

But in a new terminal ruby -v again shows:

ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]

I don't want to change the default Ruby version every time.

cat ~/.bash_profile returns

[[ -s "$HOME/.profile" ]] && source "$HOME/.profile" # Load the default .profile

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

I'm not sure what command you're using to change the ruby version in rvm, you didn't specify. My hunch is you're using rvm use , this is only temporary for the shell session. To change it permanently use rvm default :

rvm --default use ruby-2.1.0

This change will persist to new shell sessions.
