问题
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?
回答1:
The only fix is hack apparently. I tried the script mentioned and it worked
OSX 10.8 xcrun (No such file or directory)
回答2:
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.
