Stuck building application

I installed everything using the package manager, but I think there's something wrong with my path. Is anyone familiar with this?

Aristides-Staffieris-MacBook-Pro:~ aristidesstaffieri$ rvm use 1.8.7
Using /Users/aristidesstaffieri/.rvm/gems/ruby-1.8.7-p374
Aristides-Staffieris-MacBook-Pro:~ aristidesstaffieri$ rails new treebook

That is a path problem. Do you have [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" in your .bash_profile or .bashrc?

I don't, it returns "directory does not exist". I'm pretty new to the command line though, not sure where I went wrong.

Where do you have rvm installed? Did you do a single user installation or multiple user installation?

I did a single user installation, I think just in my user folder. Does it get installed where I unzipped the package manager?

Aristides-Staffieris-MacBook-Pro:~ aristidesstaffieri$ ls

No problem. What does ls .rvm/scripts show?

Does source .rvm/scripts/rvm work? If so, what do echo $HOME and echo $PATH show? Are you by chance using zsh (I use oh-my-zsh).

Seems like an rvm file is missing. I would try removing the .rvm folder and reinstalling rvm using the curl command on the website, curl -L https://get.rvm.io | bash -s stable. Personally, I use rbenv.
