Please provide more information. Like what did you run to get this. How do you install your gems and how do you execute your programs. From top of my head and with no info, but from experience this looks like you install gems as one user and execute your programs as another. – Saša Zejnilović

The information provided is too little to give a precise answer though to give a small summary of possible problems:

Different user trying to run the command. Versioning issues with Ruby, (trying to use version 2.0.0 when you may have a newer version of brew?)

Also the actual error: /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- mach (LoadError) May be due to a mistype? or incorrect name calling? as the error is saying that there is no such file to 'require'

Uninstalled brew and again installed it. It works for me. to uninstall brew i used following command :

function abort {
  echo "$1"
  exit 1
}

set -e

/usr/bin/which -s git || abort "brew install git first!"
test -d /usr/local/.git || abort "brew update first!"

cd `brew --prefix`
git checkout master
git ls-files -z | pbcopy
rm -rf Cellar
bin/brew prune
pbpaste | xargs -0 rm
rm -r Library/Homebrew Library/Aliases Library/Formula Library/Contributions 
test -d Library/LinkedKegs && rm -r Library/LinkedKegs
rmdir -p bin Library share/man/man1 2> /dev/null
rm -rf .git
rm -rf ~/Library/Caches/Homebrew
rm -rf ~/Library/Logs/Homebrew
rm -rf /Library/Caches/Homebrew
