Failed to install command line tools on OSX Mavericks
Install them from here. You must be a registered developer.
Other solution is: in xcode click Xcode>Open Developer Tool>More Developer Tools
This should then take you to a link which will require a developer Apple ID sign in. From there, you'll be redirected after authenticating to https://developer.apple.com/download/more/ where you can manually download and install the Command Line Tools.
The tools are still free, but xcode-select --install is no longer supported.
To install the latest command-line developer tools from https://developer.apple.com,
- Applications -> App Store -> Search -> XCode -> Install ... install XCode if you don't have it.
- Open XCode and close any pop-ups
- Go to the Xcode menu > Open Developer Tool > More Developer Tools... this opens the correct website.
- Find the newest version, download the dmg and install the package. The filename you're looking for is similar to "Command Line Tools (OS X 10.9).pkg"
