Homebrew (mac) : Reinstallation failure

Posted on

QUESTION :

Ok so I was having problems with homebrew where it would give me an error when I use any brew command, so I decided to reinstall homebrew. I used the most standard uninstallation commands you see on the internet.
After checking the brew command isn’t recognized by the console, I installed homebrew again.

This is what happened.

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

When I execute “brew”, this is what is says.

localhost:~ ~~~~~~~~$ brew

It would be very nice if any of you could help me. Thanks.

ANSWER :

I had a similar problem and it was because I had rbenv installed but hadn’t added the paths to my $PATH environment variable.

If you use bash then try the following:

  • Add eval "$(rbenv init -)" to your ~/.bash_profile.
  • Check that ~/.rbenv/bin and ~/.rbenv/shims are in your $PATH by running echo $PATH

If you use Fish Shell then you need to load rbenv in a different way. Add the following 3 lines to your ~/.config/fish/fish.config file:

set PATH $HOME/.rbenv/bin $PATH
set PATH $HOME/.rbenv/shims $PATH
rbenv rehash >/dev/null ^&1
