I have exactly the same error as above, and have no idea what to do about it. I will update this thread if I find anything. I am running an M2 MacBook with Ventura 13.2.1.

I had the same problem and it took me a few hours to fix it. The cause of this problem is that the installation of the library depends on cython3.0.0 version, and then cython3.0.0 version compilation bug caused.

1. Uninstall cython, brew remove cython.
2. Modify the ceph-client.rb file and delete the cython dependency. (This is brew implementation to install ceph-client library entry file, because can not change the official source file, so can only change own local cache file. Use "sudo find /|grep ceph-client.rb" to find the ceph-client.rb file location)
3. Manually install a lower version of cython, pip3 install "cython<3.0.0"
4. Re-install ceph-client, brew install ceph-client

@gf0842wf would you be able to list steps for removing the cython dependency?

I removed the depends line and the ENV line, but this causes issues with cmake.

 19   # depends_on "cython" => :build
...
 58     # ENV.prepend_create_path "PYTHONPATH", "#{Formula["cython"].opt_libexec}/lib/python#{xy}/site-packages"

I only deleted one line. After you removed the line, did you install the lower version of cpython again?

      macFUSE must be installed prior to building this formula. macFUSE is also necessary
      if you plan to use the FUSE support of CephFS. You can either install macFUSE from
      https://osxfuse.github.io or use the following command:

      brew install --cask macfuse
