You may not be, but that doesn’t mean `gcc` isn’t. And it doesn’t appear to be Xcode directly which is the issue - rather something to do with the pathing it sets up — William Miller, Jan 21 '20 at 08:32

According to https://tips.tutorialhorizon.com/2015/10/01/xcrun-error-invalid-active-developer-path-library-developer-commandline-tools-missing-xcrun/ you should run xcode-select --install

I’d recommend linking to [this answer](https://apple.stackexchange.com/a/254381) on apple stack exchange instead (or to the corresponding question). The answer there is the same but there is more explanation and less ad clutter, not to mention the stack exchange answer is for Catalina not El Capitan – William Miller Jan 21 '20 at 08:37
