Brew won't upgrade on Mojave

Question

I have installed:

• Xcode 10
• Command Line Tools (macOS 10.14) for Xcode 10 Beta and Beta 2

• macOS_SDK_headers_for_macOS_10.14.pkg using this:

  sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
  

I have also opened Xcode 10 and waited for it to install components.

Brew still gives me the error:

Error: The Command Line Tools header package must be installed on Mojave.
The installer is located at:
/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

Here is brew config

What should I do next to get Brew to work?

Answer 1

Same situation. Also just got an update through Software Update for Command Line Tools for Xcode 10 Beta 3.

I installed that and re-installed updated SDK headers and brew config now shows CLT headers, yeah!
