RVM problem with default ruby version

when i execute following command

$ rvm --开发者_运维技巧default use 1.9.2
$ ruby -v

i got following result:

ruby 1.8.7 (2010-06-23 patchlevel 299) [i686-linux]

i can't understand why is not

ruby 1.9.2p0...

If u installed correctly, most likely its is path problem.

Solution 1: Manually add the ruby1.9.2.p0 path into ur $PATH

Solution 2: Try run:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

Type rvm info.

All paths should reflect rvm's installation in your home directory.

If not, odds are good you didn't follow the "Post Install" directions for rvm, and need to go through them, and the troubleshooting section that follows it.

Maybe you should to try

rvm reload

or try to type

 rvm info

hope that will help you

Maybe you should invoke

rvm reload

or try to open up a new shell and then again

ruby -v

hope that works for you...

You can try running which ruby to see where your ruby is running from. If you've set up your rvm correctly and followed all the steps, it should look something like /home/username/.rvm/rubies/ruby-1.9.2-p136/bin/ruby. Also, make sure you added the line to your .bashrc file as specified in rvm-install notes.

I've found this rvm setup tutorial to work flawlessly on several different machines: http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you, including Ubuntu, Fedora, and even on a Mac (with a few adjustments).
