ERROR installing dbx - pip install dbx - pipenv error cffi

Question

I am trying to set a connection with Visual Studio Code with Databricks using pyenv following these instructions: https://docs.databricks.com/dev-tools/ide-how-to.html

When I try to install dbx (pip install dbx) I have an error on the cffi package. I am using Python 3.8.9 and pip 23.00.

The blocks of errors I get are:

Building wheels for collected packages: cffi
  Building wheel for cffi (setup.py) ... error
  error: subprocess-exited-with-error
  
  × python setup.py bdist_wheel did not run successfully.

      error: command '/usr/bin/clang' failed with exit code 1
      [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.

× Encountered error while trying to install package. ╰─> cffi

In case it helps, the machine-software specifications are (sw_vers output):

ProductName:    macOS
ProductVersion: 12.3
BuildVersion:   21E230

I am not a developer and I do not have much control about these things but I have read that it may be related to gcc. Here is the output of gcc --version:

Apple clang version 13.1.6 (clang-1316.0.21.2.5)
Target: arm64-apple-darwin21.4.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

On the other hand, it is clear that cffi is not installed since pip show cffi:

WARNING: Package(s) not found: cffi
