Homebrew - bad interpreter: No such file or directory
提问by Alex
Like an idiot, I managed to delete my system ruby install.
像个白痴一样，我设法删除了我的系统 ruby 安装。
I've re-installed xcode, and also installed RVM
我重新安装了 xcode，还安装了 RVM
Doing this:
这样做：
$ which ruby
returns this:
返回这个：
/Users/alex/.rvm/bin/ruby
However, Homebrew still seems to be broken:

$ brew
-bash: /usr/local/bin/brew: /usr/bin/ruby: bad interpreter: No such file or directory

The system ruby on OS X is symlinked to the Ruby.framework. Since you reinstalled Xcode, it should be installed, but you need to restore the symlinks.
OS X 上的系统 ruby 符号链接到 Ruby.framework。由于您重新安装了 Xcode，它应该已安装，但您需要恢复符号链接。
First, check that this file exists and works.
首先，检查此文件是否存在并有效。
$ /System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby -v
ruby 1.8.7 (2010-01-10 patchlevel 249) [universal-darwin11.0]
If that command works, you should be able to setup the sym links again
如果该命令有效，您应该能够再次设置符号链接
cd /usr/bin
sudo ln -s ../../System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby /usr/bin/ruby
sudo ln -s ../../System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/erb /usr/bin/erb
sudo ln -s ../../System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/gem /usr/bin/gem
sudo ln -s ../../System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/irb /usr/bin/irb
sudo ln -s ../../System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/rake /usr/bin/rake
sudo ln -s ../../System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/rdoc /usr/bin/rdoc
sudo ln -s ../../System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ri /usr/bin/ri
sudo ln -s ../../System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/testrb /usr/bin/testrb
This should get you started, hopefully I haven't forgotten any of the binaries that need linked. There are other suggestions to reinstall ruby here: https://superuser.com/questions/171433/is-it-possible-to-reinstall-fix-mac-os-xs-system-ruby-without-doing-a-complete
这应该让你开始，希望我没有忘记任何需要链接的二进制文件。还有其他建议在这里重新安装 ruby：https: //superuser.com/questions/171433/is-it-possible-to-reinstall-fix-mac-os-xs-system-ruby-without-doing-a-complete

brewis hardcoded to use the system ruby. You could try change brew's shebang (the first line) to /usr/bin/env ruby, but it's not guaranteed to work with anything but the system Ruby (I'm not sure it's fully compatible with Ruby 1.9).
brew硬编码以使用系统 ruby。您可以尝试将brew的shebang（第一行）更改为/usr/bin/env ruby，但不能保证除了系统 Ruby 之外的任何东西都可以使用（我不确定它是否与 Ruby 1.9 完全兼容）。
Or you could reinstall your system Ruby, which should be possibly by reinstalling OS X.
或者您可以重新安装系统 Ruby，这可能是通过重新安装 OS X 来实现的。

If you don't want to have to reinstall the system ruby, the following should do the trick.
如果您不想重新安装系统 ruby，以下应该可以解决问题。
IMPORTANT:replace MY_USER_NAMEwith the name of your home folder, which is the "short name" of your user in OS X.
重要提示：替换MY_USER_NAME为您的主文件夹的名称，即您的用户在 OS X 中的“短名称”。
sudo ln -s /Users/MY_USER_NAME/.rvm/bin/ruby /usr/bin/ruby
