Install/Uninstall Homebrew On Mac & Fix “Brew: Command Not Found”

Homebrew lets you install the stuff that didn’t come out of the box with your Mac. It works the same way as apt-get on Debian/Ubuntu system or yum on CentOS/Red Hat.

You can install almost all the Linux libs and tools on your Mac. Not only that, you can create your packages to install on other Mac systems. It has pure Git and Ruby underneath, so hack away with your knowledge and creativity.

Now coming to the point.

-bash: brew: command not found

If you got this error while brewing a package on your Mac, then you are not alone. The reason is simple. Homebrew is not installed on your system.
