Recover pre-installed ruby to Mac OS X

Question

I know it should never be done, but I accidentally removed the folder /usr/bin/ruby from my Mac OS X. With that I lost all pre-installed ruby files. Now when trying to install Homebrew, for instance, I get the error:

-bash: /usr/bin/ruby: No such file or directory

How can I get pre-installed ruby back to /usr/bin?

Well hopefully you have a backup? If not I suppose you'll have to reinstall to get the Apple provided Ruby back. — Andrew Marshall, Jun 12 '12 at 03:20

Just install rvm and get most updated ruby. Even because the one shipped with OS X is rather obsolete (it should be 1.8.7 if I remember correctly).

There's no need to reinstall the bundled one when you can install an updated version in just a couple of minutes.

how are you sure there is no need to re-install the system ruby? what about xcode or osx apps that rely on ruby, won't they try run ruby from the default location? – speedynomads Jul 04 '13 at 07:51

Could you just download it from: ftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.6-p111.tar.bz2

and then compile it into your /usr/bin directory.

There still might be permission/ownership issues you'd have to deal with.

Installing it as root using sudo, or using chmod, chown as needed. – Noah Clark Jun 19 '12 at 19:07
