Fix gyp: No Xcode or CLT version detected! error

If you have this error, and you running xcode-select --install tells you you have them installed, you will need to remove them and then install them again, you can do that with.

sudo rm -rf $(xcode-select --print-path) && xcode-select --install

The first part with get the path where xcode-select was installed and remove it and the second part will install it again.
