Installing in Homebrew errors

Question

Attempting to install rvm and ruby 1.9.2

I already installed homebrew and git, but couldn\'t get complete updates because I kept getting permission errors. Re-install

Answer 1

I had this issue after upgrading to Mavericks, and this page was the top search result when googling the error message. I continued searching and found this answer on stack overflow.com. Put concisely, it is:

sudo chmod a+w /usr/local/Cellar

This fixed the issue for me, and as it only changes permissions for the specific path referenced in the error message, seemed unlikely to have negative side effects with other installations.

I'm putting this answer here for anyone else who may find this page first like I did. However, credit should go to jdi.
