Cannot find Ruby or Rails in my computer after installing Heroku

Question

I just started to learn Rails from railstutorial.org. After installing Rails I cerated an app, set up git, installed Heroku gem, and uploaded SSH key to heroku.

After that, I turned off my computer and a few hours later I came back to continue with the next steps. First I ran heroku create --stack cedar.

Then,

git push heroku master I get the following error message:

[~ (master)]$ git push heroku master fatal: 'heroku' does not appear to be a git repository fatal: The remote end hung up unexpectedly

Same thing is happening for commands like rails heroku gem etc.

Also, I cannot find neither Ruby or Rails in my system. When I ran ruby -v I get

The program 'ruby' can be found in the following packages: * ruby1.8 * ruby1.9.1 Try: sudo apt-get install <selected package>

Is this happening because I am running Ruby 1.9.3p125? Please help.

just type

rvm gemset list

rvm use 1.9.3@(you_gemset) --default

EDIT: i've looked this tutorial, and there he's created gemset: rails3tutorial2ndEd then just type: rvm use 1.9.3@rails3tutorial2ndEd --default

You probably haven't set ruby 1.9.3 as your default ruby with rvm. You can do this by typing in the command line:

rvm use 1.9.3 --default

This should solve your problem.

Thanks for the suggestion, I did that earlier. Didn't set a default gemset. – tayeed Mar 20 '12 at 15:16
