Installed Rails but the rails command says it's not installed

Question

I'm using Ubuntu 9.10 Karmic Koala and Ruby 1.9.1.

I installed Rails using sudo gem install rails, which installed all the libraries for me.

When I type rails in the terminal it says.

The program 'rails' is currently not installed. You can install it by typing: sudo apt-get install rails rails: command not found

I can find rake, which is under rake1.9.1, but Rails is nowhere to be found, can someone point me in the right direction?

Edit: path to ruby isn't the problem, the problem is where is rails? how do I execute it? rails just doesn't work, where does the exectuable lives?

Answer 1

As others say, this may very well be a PATH variable issue on your bashrc/bash_profile file.

You can learn how to change PATH..

You can get the current PATH variable by typing echo $PATH
