Brew Permission Denied on Mac OS X

This is a common error that might occure while you try to install a brew package or when you try to do a brew link which could say Error: Permission denied

It’s too bad that unless you properly look on the log it outputs on the console, you won’t notice that the brew link has actually failed.

Anyway, what happens most of the time is, When we run an application installation with super user permissions, sometimes it actually modifies the permissions on /usr/local which will they be a problem for a application that’s not running with sudo permissions.

Luckily there’s a easy way to fix this, just run the below commands on terminal and brew should start working properly.

sudo chown -R "$USER":admin /usr/local

Also you might have to run this too in some cases

sudo chown -R "$USER":admin /Library/Caches/Homebrew

Some Sundays move at their own slow pace, and yesterday was one of them. I went into the weekend feeling excited to refactor a piece of code that’s been bothering me for weeks. But by Sunday evening, the work was still unfinished and instead of accepting that, I spent way too much time complaining to
