how to use 'brew' for install gcc on ubuntu

Question

when i want to run brew install gcc on Ubuntu 18.04, i got an error:

Error: Running Homebrew as root is extremely dangerous and no longer supported.
As Homebrew does not drop privileges on installation you would be giving all
build scripts full access to your system.

You may need to reinstall brew:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)"

And then you can run:

brew install gcc
