brew on OSX 10.10.1 not working, ruby kernel_require error

Question

I recently updated my Mac's copy of OSX from 10.6 to 10.10. Everything seems to be working fine except for brew.

my_mac:local my_user$ brew install wget
/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 -- global (LoadError)
    from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'
    from /usr/local/Library/brew.rb:15:in `<main>'

Since brew is based on Ruby I believe there's some problem with the system's install of Ruby, but I'm not sure how to approach it. I've tried to re-install the most recent version of Ruby and then Homebrew, but when Homebrew gets to

brew cleanup

It throws the same Ruby error.

Thanks!

Seems to be similar to this http://stackoverflow.com/questions/24652996/homebrew-not-working-on-osx Have you tried what they suggest there? — Scymex, Jan 20 '15 at 21:54
Try `cd /usr/local; git fetch; git reset --hard origin/master`. — Tim Smith, Jan 21 '15 at 05:35
@MarcoPrins I did, it did not work. It resulted in the same Ruby error. — pjc, Jan 22 '15 at 02:06
@TimSmith Unfortunately I get `fatal: Not a git repository (or any of the parent directories): .git` — pjc, Jan 22 '15 at 18:55

I've just had this problem too and the problem was corrupted permissions:

$ cd /usr/local
$ find . -mindepth 1 -user root

If any files or directories related to homebrew show up, you should use chown to fix the permissions.

it turned to be permission problem. Here is the command I used to fix the problem based on the answer from quaestor

$ cd /usr/local<br>
$ find . -mindepth 1 -user root -exec chown *xxx* {} \ ;

Where *xxx* is the user you want to change to. You may want to only do chown for directories related to brew.

As others have mentioned it is because of corrupted permissions You can fix it using the following command:

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

It changes the permissions of /usr/local directory.
