RUBY: rvm not recognized

Hi, I am having trouble following along..

Brents-MacBook-Pro:treebook BrentSullivan$ ruby -v ruby 2.0.0p353 (2013-11-22 revision 43784) [x86_64-darwin13.1.0] Brents-MacBook-Pro:treebook BrentSullivan$ rvm use 2.0.0 -bash: rvm: command not found

If I skip entering rvm in the console, then I can go straight to entering rails server and it typically works, although I have been getting an error message recently, and do not know how to resolve. Any ideas?

The following error pops up in my browser when I attempt to confirm I am riding Ruby on Rails:

ActiveRecord::PendingMigrationError Migrations are pending; run 'bin/rake db:migrate RAILS_ENV=development' to resolve this issue.

Rails.root: /Users/BrentSullivan/treebook

RVM just manages your versions of ruby so you can switch between them on the fly and it makes it easy to install different versions. You don't need it but its nice to have.

RVM is quite handy and I recommend you try and get it working. first be sure you have rvm installed by running this command:

\curl -sSL https://get.rvm.io | bash -s stable

that will get the most recent stable version of RVM.

if you still get the rvm not found message after that RVM may not have been added to your PATH correctly. open up your .bash_profile file in sublime text/text editor of your choosing and see if you have anything related to rvm in there

$ cd ~
$ subl .bash_profile

in my .bash_profile ive got the following line

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

it should add that line when it installs though. If not go ahead and copy it in your file and save it. then restart your terminal and see if it works

Make sure you actually have rvm installed. also run rake db:migrate in your terminal

Thanks.

Why do I need rvm?

I essentially killed the session and deleted my treebook directory, then started from scratch and it works now, so not sure where I went wrong.
