bash __git_ps1 command not found

Question

I am a beginner trying to setup a developer environment on my new Mac following the steps from this link: http://vanderveer.be/setting-up-my-perfect-developer-environment-on-osx-10-8-mountain-lion-10-8-2-final-edition/.

After executing the files from git, my terminal window now shows:

rbenv: version `1.9.3-p194' not installed
-bash: __git_ps1: command not found

The first line only shows when I open a new terminal window, while the second shows everytime I press return no matter what I type into the terminal.

I have read through many questions on stackoverflow and tried to mimic their solutions to no avail. I think I've made a mistake in installing the package from git as I am not so experienced and I think now I may have messed up the configurations, and was also wondering if there is any way to go back to default settings for bash?

Many thanks! Allen

If you've not installed a newer version of Git on your Mac, start by doing that. You can grab the download from here: http://git-scm.com/download

Once it's installed, you should source git-completion.sh and git-prompt.sh from your ~/.profile (or ~/.bashrc, if you have it):

source /usr/local/git/contrib/completion/git-completion.bash
source /usr/local/git/contrib/completion/git-prompt.sh

That should fix the __git_ps1 error.

I'm not a Rubyist, but the rbenv error is coming from the fact that the setup in the dotfiles you are following is trying to set the default Ruby version to "1.9.3-p194". The rbenv tool is there to make a number of different Ruby versions available, but you have to install them first. In your case, I think you need to run this:

rbenv install 1.9.3-p194

After that, the version will be available, and you shouldn't see the warning anymore.
