I don\'t know how to install the Command Line Tools on OSX Mavericks. Or better: I know how to do it (I just did it on another MacBook), but something goes wrong this time.
If you are not able to install the XCode CLI using terminal command
sudo xcode-select --install
Just download the command line tool from Apple developer website (below link) https://developer.apple.com/download/more/ And install it manually.
