ruby - How to install command line tools on OSX Mavericks

Question

I am running OSX Mavericks (10.9) and while trying to update a bundle in rails, I get the following error message:

"You have to install development tools first."

I have Xcode already installed and there seems to be no option to install the tools from within the Xcode 4.6. How can I download and install command line tools via terminal?

Answer 1

Incase, while trying to update a bundle, you get an error "You have to install development tools first." on OSX Mavericks (OSX 10.9), but you already have Xcode installed, you can still manually install the dev tools via terminal:

xcode-select --install

Do that and follow on-screen instructions. Your problem will be solved.
