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.

Answer 1

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
