I have a Mid 2015 MacBook Pro running macOS High Sierra 10.13.3.

I tried starting up a new project and none of my commands seem to work.

I always get this error:

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), 
missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

Seems pretty straight forward, Xcode Command Line Tools missing. Except installing it seems to not work/have no effect.

I enter: xcode-select --install, press install, agree to the agreement, it downloads, installs, gives me a nice The software was installed but if I try any command again (like brew update or brew upgrade); I get the same error. (I tried rebooting, but to no effect).

How do I resolve this issue? All I could find on Google is people saying Install Xcode Command Line Tools.

  • Does the output of brew config outputs a value corresponding to CLT: key? – Nimesh Neema Apr 8 '18 at 10:36

  • As can be seen from the output, Homebrew doesn't recognise the installation of Xcode and CLT. Have you installed Xcode via DMG or from the Mac App Store? – Nimesh Neema Apr 8 '18 at 10:45
  • I don't have Xcode (never needed it), installed CLT via the terminal as I explained in my original question. As far as I know Xcode isn't necessary for homebrew. Never had it and it always worked fine... Unless it's a new requirement? – Frenchmassacre Apr 8 '18 at 11:04
  • Yes, Xcode isn’t required to install CLT and Homebrew. – Nimesh Neema Apr 8 '18 at 11:11

Okay, After a full day of attempts, re-installing homebrew and all... found a solution which I should have tried a lot earlier in all honesty. Leaving it here if anyone else has the same problem in the future:

Doing xcode-select --install showed everything as being installed correctly but I just couldn't confirm that anywhere. I downloaded the CLT as a pkg from the apple developer website (https://developer.apple.com/download/more/) and installed it the old fashioned way. CLT is now installed and homebrew is detecting it just fine.

Brew Config now:

Thanks Nimesh for helping me!

  • i had the same issue - running xcode-select --install fixed it for me but installing CLT manually would also do the trick! – Lloyd Oct 1 '18 at 9:28

I had to check configuration of location as explained here to make it work:

You can just select command line tools from the XCode Preferences show in below screenshot.

You will be prompted for password.

  • Useful if you have xCode installed (which is not my case; don't use it and can't afford 10GB of storage on something I don't use..) my question was specific to no-xCode installed... Thanks for the answer though, could help others :) – Frenchmassacre Sep 16 '18 at 11:23

  • This worked for me, when setting up the Glasgow Haskell Compiler! Very easy fix! – Woodstock Dec 26 '19 at 3:27

If the above answer doesn't fully fix the problem you can also check Brew Doctor mine was also complaining that Xcode.app was in the wrong place and to fix suggested the fix.

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

My /Applications folder had somehow changed from ~/ to /


Also ran into this. Turns out homebrew had installed my Xcode cmd line tools in /usr/bin. My IntelliJ looks for the cmd line tools at /Library/Developer/CommandLineTools/usr/bin/ So what I did was cd into /Library/Developer/CommandLineTools/usr/bin/ then did a

cp /usr/bin/* ./

and my cmd line tools were copied in. After that, IntelliJ had no more complains.

  • It's really strange to copy all commands in /usr/bin/. – DawnSong Aug 23 '19 at 6:42
