homebrew not working on OSX

 

Getting this error when i run the brew command on terminal. Need help resolving. 

 /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 -- utils/popen (LoadError)

here are my env gem settings:

  • RUBYGEMS VERSION: 2.0.14
  • RUBY VERSION: 2.0.0 (2014-02-24 patchlevel 451) [universal.x86_64-darwin13]
  • INSTALLATION DIRECTORY: /Library/Ruby/Gems/2.0.0
  • RUBY EXECUTABLE: /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby
  • EXECUTABLE DIRECTORY: /usr/bin
  • RUBYGEMS PLATFORMS:
  • ruby
  • universal-darwin-13
  • GEM PATHS:
  • /Library/Ruby/Gems/2.0.0
  • /Users/ronaldkwan/.gem/ruby/2.0.0
  • /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/gems/2.0.0
  • GEM CONFIGURATION:
  • :update_sources => true
  • :verbose => true
  • :backtrace => false
  • :bulk_threshold => 1000

    • The problem mainly occurs after updating OS X to El Capitan (OS X 10.11) or macOS Sierra (macOS 10.12). This is mainly because of file permission issues with El Capitan's or later macOS's new SIP process. Try changing permissions of /usr/local directory. 

    $ sudo chown -R $(whoami):admin /usr/local

    If it still doesn't work, use following steps and everything will be fine. This may be because homebrew is not updated. 

    1. open terminal  
2. $ cd /usr/local/Library/Homebrew  
3. $ git reset --hard  
4. $ git clean -df
5. $ brew update

    First, open terminal and cd /usr/local/ , and git status to see if Homebrew is clean.

    if dirty, git reset --hard && git clean -df

    then brew doctor , brew update

    If still broken, try this in your terminal: 

    $ sudo rm /System/Library/Frameworks/Ruby.framework/Versions/Current
$ sudo ln -s /System/Library/Frameworks/Ruby.framework/Versions/1.8 /System/Library/Frameworks/Ruby.framework/Versions/Current

    This will force Homebrew to use ruby 1.8 from system

    Uninstall homebrew: 

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

    Then reinstall 

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

    Warning: This script will remove: /Library/Caches/Homebrew/ - thks benjaminsila
