Greetings and Salutations, Note that Xcode Command Line Tools is not the same as Xcode IDE. In fact, only Xcode CLI Tools are required, which are light-weight compared to the IDE.
Regarding your error, this is symptomatic of an Xcode update tied to an OS point-release. Note in the session information 10.15.1 (the .1 being the bump) R version 3.6.1 (2019-07-05) Platform: x86_64-apple-darwin15.6.0 (64-bit) Running under: macOS Catalina 10.15.1 Both of the commands highlighted are accurate. Though, the order should be changed to: sudo xcode-select --reset sudo xcode-select --install The reset changes back to using the default command line tools path. This was needed for Mojave.

I think I have everything up to date: macOS 10.15.1 Catalina with Xcode downloaded and installed via the App store.

This StackExchange discussion also said, "If the above alone doesn't do it, then also run: xcode-select --reset". However, before I do that, I thought I'd ask here if anyone else is having a problem like this. And if yes, and if they've fixed it, what did they do to fix it?
