xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools) after installing macOS Big Sur

I've installed macOS Big Sur! This means breaking everything my development environment again.

If you get this error:

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

   Exiting due to failure

You'll need to install the XCode development tools again with the following command.

xcode-select --install
