Sometimes I get this message.
The bottle needs the Xcode CLT to be installed.
That’s weird because I’m running Xcode 10 on MacOS Mojave and CLT are installed. I found instructions for installing Xcode CLT so I tried that.
$ xcode-select --install xcode-select: error: command line tools are already installed, use "Software Update" to install updates
I’m not sure what it means by “Software Update”. I definitely have the latest release of Xcode 10.
Xcode is convinced that CLT is installed.
brew config can find some of the tools like
git but not CLT.

brew doctor told me that I should update CLT from the App Store.
Warning: A newer Command Line Tools release is available. Update them from Software Update in the App Store.
There aren’t any updates available in the App Store because I have the latest!
