Yosemite下homebrew不可用

Oct 26, 2014

升级到Yosemite后brew的相关操作会有错误提示，如下：

/usr/local/bin/brew: /usr/local/Library/brew.rb: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby: bad interpreter: No such file or directory
/usr/local/bin/brew: line 23: /usr/local/Library/brew.rb: Undefined error: 0

此时将此路径下文件/usr/local/Library/brew.rb的第一行

#!/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -W0

写死的1.8版本修改为current

#!/System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby -W0

即可。
