Ruby 2.0 is running, but Rails 4 doesn't see it

What am I doing wrong??

****@ubuntu:~/ruby/things_i_bought$ rake db:migrate

Rails 4 prefers to run on Ruby 2.0.

You're running
  ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-linux]

Please upgrade to Ruby 1.9.3 or newer to continue.

Check:

$ which rake
$ which rake --version

I suspect you aren’t executing the one in the Rails.root/bin directory.

that’s 2.0 correct?

Thanks for the help, BTW.

Yes, it is.

Wish I could offer an answer…

nope, thanks though

Hmmm

I don’t see any output of which ruby, probably missordered
PATH-variable?
Please check.

"Also, when I type in which ruby it freezes the console. "

I think whatever ruby you think you’re running is damaged. Based on the
rails output about needing 2.0 but having 1.8.7 I guessing you’ld be
well
served by uninstalling 2.0 and redoing the install. How about if you
type
“ruby --version” in your console, does that also hang?

[email protected]:~/ruby/things_i_bought$ echo $PATH
/home/sean/.rvm/gems/ruby-2.0.0-p0/bin:/home/sean/.rvm/gems/[email protected]/bin:/home/sean/.rvm/rubies/ruby-2.0.0-p0/bin:/home/sean/.rvm/bin:/home/sean/sbt/bin:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/bin/:/home/sean/AWS-ElasticBeanstalk-CLI-2.3.1/eb/linux/python2.7/:/home/sean/anaconda/bin/

and here’s the relevent section of my .bashrc file:

PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting

[[ -s “$HOME/.rvm/scripts/rvm” ]] && . “$HOME/.rvm/scripts/rvm” # This
loads RVM

Also, when I type in which ruby it freezes the console.

In that case you have a serious problem that is nothing to do with
ruby itself. All which does (AFAIK) is to look in the path for the
file to execute.

no that works. I was typing it with the grave accents. I guess grave
accents freeze my console.

Still, I don’t know how to get Rails 4 to recognize Ruby 2…

Okay, I tried that. I uninstalled all previous version of ruby with rvm.
Now the only version of ruby on my machine is 2.0:
[email protected]:~/ruby$ rvm list

rvm rubies

=* ruby-2.0.0-p0 [ i686 ]

=> - current

=* - current && default

* - default

[email protected]:~/ruby$

But, it’s still not working. I also tried uninstalling and reinstalling
rails4 through gem. Now rails 4 is the only version of rails on my
machine. I think next I’ll try uninstalling rake. Maybe it’s rake.

Thanks anyway.

1 check if you have .ruby-version file
2 check the contents of your Gemfile for references to ruby 1.8 or
Force
it to use ruby 2.0
3 rm Gemfile.lock and rebuild

reinstalled rvm and rubygems. Now everything works… Case closed. Thank
you everyone for the help. You have my eternal gratitude.
