[PyQt] PyQt 5.13.2 build error: module 'sipbuild.api' has no attribute ‘prepare_metadata_for_build_wheel'

[FX]

> The documentation does not have anything pyqtbuild. It does have something about  PyQt-builder, but it’s not clear it is the  same as pyqtbuild? And even so, it’s only mentioned in the "Bundling Qt Using pyqt-bundle”, which is not what I am trying to do.

Documenting my progress: apparently this is it. Installing PyQt-builder allows sip-install to progress further.

Now the build fails with:

Generating the pyrcc5 script...
Generating the pyuic5 script...
Generating the .pro file for the Qt module...
sip-install: An internal error occurred...

It is trying to write to the sip installation directory, to which it does not have access (in Homebrew, packages are not allowed to write to other packages’ folders).

Previously we configured with:

-    args = ["--confirm-license",
-            "--bindir=#{bin}",
-            "--destdir=#{lib}/python#{version}/site-packages",
-            "--stubsdir=#{lib}/python#{version}/site-packages/PyQt5",
-            "--sipdir=#{share}/sip/Qt5",
-            # sip.h could not be found automatically
-            "--sip-incdir=#{Formula["sip"].opt_include}",
-            "--qmake=#{Formula["qt"].bin}/qmake",
-            # Force deployment target to avoid libc++ issues
-            "QMAKE_MACOSX_DEPLOYMENT_TARGET=#{MacOS.version}",
-            "--qml-plugindir=#{pkgshare}/plugins",
-            "--verbose”]

Could you advice what would be the closest options for this? Many of these options do no exist anymore…
