I've upgraded OSX Lion to Mountain Lion and reinstalled the Command Line Tools (as the upgrade deleted them). From then xcrun does not work anymore. The xcode-select is set to /usr/bin, the binaries are in that directory too, but if I run xcrun with an argument (ex. xcrun gcc) it displays this:

 xcrun: Error: failed to exec real xcrun. (No such file or directory)

I've tried setting the path again with xcode-select and reinstalled the CLT. Nothing helped.

Any suggestions how to fix this?

  • Bump. I've tried uninstalling the command line tools with the script provided in this article: cocoanetics.com/2012/07/… and I'm still having the same problems. I reinstalled the command line tools using the separate download. Still have the same problem. Commented Aug 16, 2012 at 18:09

I had the same problem. Originally I was doing the following for my xcode-switch:

$ sudo xcode-select -switch /Applications/Xcode.app/

However what was really needed was:

$ sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer/

This fixed the problem for me. Not sure if sudo is needed.

Worked for me, but I had to replace Xcode.app with Xcode_4.4.1.app because I renamed my Xcode.app file.
Unfortunately, this won't work for OP's situation (mine too) where the standalone Command Line Tools are installed in /usr/bin.
After struggling for days with this issue I found in this post my answer. Thanks a lot!. It should be marked as accepted.
This fixed an issue I was having with the TestFlight desktop app failing to build the IPA to upload, thanks!
If you are using Xcode5 preleases, you'll have to explcitly point to them, sudo xcode-select -switch /Applications/Xcode5-DP5.app/Contents/Developer/

The only fix is hack apparently. I tried the script mentioned and it worked

OSX 10.8 xcrun (No such file or directory)

Just made a clean reinstall of my Mac. Mountain Lion, command-line tools, homebrew, rvm. And I came across this issue. The xcrun hack, though quite ugly, works well. Thanks a lot for pointing this out, I wouldn't have found the other discussion otherwise.
