Homebrew thinks Xcode CLT aren't installed

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 clang and git but not CLT.

$ brew config

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!

Any ideas?

This looks like a bug, could you file it at https://github.com/homebrew/brew? (If nobody did already)


Hi, I Have the same problem! How u done it?

I’m sorry but I don’t know. I think the problem just solved itself. It was a long time ago!

I write for everyone who also came across this thread in search of answers. I solved this problem as follows:
Installed the corresponding version of my Xcode command line tool from the official site:

Then I used brew upgrade and everything was solved. Please note that in the latest versions of Xcode, CLT cannot be installed directly from Xcode.
