Xcode – Git is not working after macOS Update (xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools)

command-linegitmacosterminalxcode

I updated to macOS Mojave (this happens on Catalina update too, and seems to potentially occur on every major update thereafter)

This morning I navigated to my work's codebase in the Command Line on my MacBook pro, typed in "git status" in the repository and received the error:

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

How do I fix git, and command line tools?

Best Solution

The problem is that Xcode Command-line Tools needs to be updated.

Solution #1

Go back to your terminal and enter:

xcode-select --install

You'll then receive the following output:

xcode-select: note: install requested for command line developer tools

You will then be prompted in a window to update Xcode Command Line tools. (which may take a while)

Open a new terminal window and your development tools should be returned.

Addition: With any major or semi-major update you'll need to update the command line tools in order to get them functioning properly again. Check Xcode with any update. This goes beyond Mojave...

After that restart your terminal

Alternatively, IF that fails, and it very well might.... you'll get a pop-up box saying "Software not found on server", see below!

Solution #2

and you hit xcode-select --install and it doesn't find the software, log into Apple Developer, and install it via webpage.

Login or sign up here:

Look for: "Command Line Tools for Xcode 12.x" in the list of downloads Then click the dmg and download.
