Enable multiple users to install software using homebrew

Question

I installed homebrew using my other user account (which I use during work), but it is impossible to install software from my newly created personal account:

$ brew install unrar
Error: Cannot write to /usr/local/Cellar

A ls -dl /usr/local/Cellar/ shows that the directory is owned by my other user account.

How do I configure homebrew to allow multiple users to install software?

Answer 1

Here's my workaround:

su - myother_user_account -c "brew install ..."

Answer 2

On the homebrew wiki, it mentions that you can install it anywere, try having local installations for each user.

Answer 3

set umaskfor each user first. (.basrc or .profile or .bash_profile)

umask 0002 # group write permition

then give group write permit ion to /usr/localrecursively:

sudo chmod -R g+w /usr/local/

then change owner to staff

sudo chgrp -R staff /usr/local

now each user who is in staff group can use brew install and other brew stuff... Mostly every user is in that group.
