Homebrew: ruby bad interpreter: No such file or directory

Written by iassael on 03/06/2014. Posted in computing, macosx

After installing 10.10 DP1 Yosemite (yeah I couldn’t resist the temptation) homebrew gave me the following error:

/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

This error can easily be fixed in the following steps:
1) Open terminal

2) nano /usr/local/Library/brew.rb

3) In the first line change “1.8” to “Current”, so it should look like this:

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

Cheers~
