      ############################
      # Package would be ignored #
      ############################
      Python recognizes 'slapdtest.certs' as an importable package,
      but it is not listed in the `packages` configuration of setuptools.
  
      'slapdtest.certs' has been automatically added to the distribution only
      because it may contain data files, but this behavior is likely to change
      in future versions of setuptools (and therefore is considered deprecated).
  
      Please make sure that 'slapdtest.certs' is included as a package by using
      the `packages` configuration field or the proper discovery methods
      (for example by using `find_namespace_packages(...)`/`find_namespace:`
      instead of `find_packages(...)`/`find:`).
  
      You can read more about "package discovery" and "data files" on setuptools
      documentation page.

note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for python-ldap
Failed to build python-ldap
ERROR: Could not build wheels for python-ldap, which is required to install pyproject.toml-based projects

Steps to reproduce:

Operating system: macos monterey 12.1, apple M1

Python version: 3.8.6

python-ldap version: 3.4.0

See #488 for that same error. I made the same mistake of confusing the error and the warning. Most likely you just upgraded macOS. That apparently remove Xcode, or at least the bits required to build python-ldap.

Simply reinstall Xcode from the App Store. You'll still the see the warning regarding slapdtest.certs, but that is just a warning and everything will build just fine.

Thank you for your reply， I change the version python-ldap==3.4.0 to 3.3.0 ,pip install success
