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

You can allow only Admin users writing into /usr/local/?

chgrp -R admin /usr/local
chmod -R g+w /usr/local
chgrp -R admin /Library/Caches/Homebrew
chmod -R g+w /Library/Caches/Homebrew

Since that each user who belongs to Admin group, will be able to install new dependencies.
