'Error: Cowardly refusing to `sudo brew install` for installing glue 0.3 for Mac OSX Mountain Lion

I'm trying to install glue 0.3 for OXS Mountain Lion and ran into this error after installing homebrew (Error: Cowardly refusing to sudo brew install You can use brew with sudo, but only if the brew executable is owned by root. However, this is both not recommended and completely unsupported so do so at your own risk.) I got this error after the first step for installing glue 0.3 ($ sudo brew install jpeg). No idea how to fix this...please help!

homebrew


Solution 1:[1]

sudo chown root /usr/local/bin/brew

Solution 2:[2]

sudo chown -R $USER /usr/local

Use the above command instead of changing the owner of brew to root.

This is the suggested method by the Owner of homebrew in https://github.com/Homebrew/homebrew/issues/9953

I solved it by NOT using sudo, and changing the permissions on whatever file it says cannot be accessed without sudo.

For example, I could not access /usr/local/Cellar, so I entered the following (as specified here: https://github.com/Homebrew/homebrew/issues/3930)

sudo chmod g+w /usr/local/Cellar
sudo chgrp staff /usr/local/Cellar

For High Sierra macOS 10.13.3 or newer.

None of the solutions given here worked for me on this version. The only (and the best) fix is to uninstall brew and install it again with the following terminal commands. Note you will lose your current kegs, so you should get a list of the installed kegs, for reinstalling them after reinstalling brew as shown below under step 1. Actually, this was a good opportunity for me to get rid of those kegs that I am no longer using:

  1. List your current kegs for reinstalling, those you wan't to keep:

    brew list

  2. Uninstall brew:

    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

  3. Reinstall brew:

    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

  4. Optionally to prevent your usage being sent to Google Analytics (Update: Fortunately, now this has been stopped, so you may skip this step):

    brew analytics off

  5. Finally reinstall your previous kegs from step 1 (or those you still want to use). Replace the text with the square brackets with the list, (i.e. brew install sqlite heroku ):

    brew install [list of kegs from step 1]

I have updated my macos to sierra and npm stopped working. Below are the steps followed to fix them.

Uninstall Node and install it from brew and follow the below steps

sudo chmod g+w /usr/local/Cellar
sudo chgrp staff /usr/local/Cellar
sudo chown root /usr/local/bin/brew
sudo brew postinstall node

This was helpful for me http://digitizor.com/fix-cowardly-refusing-sudo-error-brew/

As quoted in the text, you essentially have to change the user and group of brew to root and wheel respectively.
