Which Version of Xcode Command Line Tools to Install?

[wangjess]

I am following the "Suggested Build Environment" page found here. It says to download Xcode Command Line Tools but it doesn't specify which version.

On Apple's Developers page, there are several different versions available: here (Note: You will have to login to your Apple account to view page)

So I don't install the wrong one, asking in advance - which one to use?

Also, I am not sure if this is even required. Will Oppia installation work fine without this Xcode CLI tools?

For anyone curious -
running:
sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install

helped.
