Homebrew install permissions issue

Question

I have a standard homebrew install inside of usr/local/

When I try:

Larson-2:~ larson$ brew install postgresql
Error: Cannot write to /usr/local/Cell         


        

Answer 1

The problem can be solved by changing the directory's owner to the current user:

sudo chown -R $USER /usr/local
