xcrun: error: invalid active developer path ( /Library /Developer /Command Line Tools), missing xcrun

I upgraded to macOS Sierra, ran git status in the terminal and got the following error.

xcrun: error: invalid active developer path ( /library /developer /command line tools), missing xcrun

No bueno.

A quick google search turned up this post with the answer I sought.

Run this command to get git working again.

xcode-select --install
