There has been an error while trying to extract the source. Halting the installation.
There has been an error fetching the ruby interpreter. Halting the installation.

Your problem is in permissions:

 mkdir: /usr/local/rvm/tmp/rvm_src_7085: Permission denied

You have RVM installed in /usr/local

I am running RVM on OS X Yosemite and have my RVM installed in my home directory:

 /Users/andy...

If you want to install globally like you have it, you will probably have to use the sudo command to complete the install. But I would highly recommend NOT doing that.

You should uninstall RVM and re-install it under your home directory. That is, open the terminal and ensure that you are in your home directory:

cd ~/

will put you in your home directory. Then install RVM and DO NOT use sudo, just install it with your regular permissions. That is the whole point of RVM, to keep the versions of Ruby separate.

Here is the Stack Overflow answer for removing all traces of the old RVM from your system before reinstalling: How can I remove RVM (Ruby Version Manager) from my system? Be sure and pay attention to the part at the end about checking for modifications to your $PATH variable.
