When I enter brew doctor (or any brew command) in my terminal, I get this as a response:

-bash: /usr/local/bin/brew: /bin/sh^M: bad interpreter: No such file or directory

I have seen the ^M response before and I think it has to do with dos line ending files. Is there a way to fix this?

    This happened to me, and I figured out why. I had copied my .gitconfig over from my windows machine, and didn't change the core.autocrlf to input before installing brew. D'oh! I think Javier Roca's solution is the nicest. – Kevin Pauli Mar 27 '15 at 02:11

This worked for me:

  1. Open file /usr/local/bin/brew with vi (vi /usr/local/bin/brew)
  2. While on vi issue this commad (via esc or :) :set fileformat=unix
  3. Close file on vi via :wq!

The brew command should be OK now.

I don't know how carriage returns ended up in your brew file, but you can remove them using dos2unix or by piping it through tr -d '\r'.

Example:

tr -d '\r'  < /usr/local/bin/brew   > myfixedbrew

Once verified, you can use

mv myfixedbrew /usr/local/bin/brew && chmod a+x /usr/local/bin/brew

to replace the old one.

  • How would I use tr -d '\r'? Should I cd to /usr/local/bin then use it on the brew file? –  Apr 16 '14 at 01:47

    @mah wouldn't I need to use brew to install dos2unix? –  Apr 16 '14 at 01:50
  • Hrm. Sorry, I didn't realize dos2unix wasn't already on OS X. – mah Apr 16 '14 at 01:52
  • Ok @thatotherguy I used that command and now I am coming up with a new error: "sudo: brew: command not found". I am thinking about removing all brew then installing it again but I get this:"bash: /usr/local/bin/brew: Permission denied" when I try to delete it using: "sudo rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup" –  Apr 16 '14 at 01:54
  • @TheWaller I neglected to mention that you'd have to add back execute permissions on the file – that other guy Apr 16 '14 at 01:56
  • Thank you, finally I could install brew – Carlos Goce Sep 27 '14 at 15:47
  • this happened to me too all i did is run ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" from terminal as instructed – Alex Borsody Mar 29 '15 at 00:35
  • That fixes it. It seems the Ruby install script causes this issue on Mac OS X (just tried on Yosemite) – Jorge Orpinel Pérez Jun 12 '15 at 20:11
  • awesome that fixed it. – Damodar Bashyal Sep 05 '15 at 07:20
  • Bless on you, you helped me out. That was such a strange an uncomfortable issue for me – Bandydan Oct 15 '15 at 11:59
  • After how many decades of carriage return & line feed debates, why do we still have interpreters that even care about the difference!? – Bron Davies Mar 02 '16 at 17:53

For people using Intellij, open the gradlew file of your project. In the lower right corner of the IDE there will be one element written CRLF or LF or CR. Changed it to LF and it worked. (I'm using Windows+WSL)
