Error: homebrew/science was deprecated

[pwheregroup]

The installation via brew install qgis/qgisdev/qgis3-de gives me the following error after some warnings about python und python3 deprecations.

Error: homebrew/science was deprecated. This tap is now empty as all its formulae were migrated.

The warnings gives information who should be notified whereas the error don't.

Can someone explain or solve the issue please?

This is because homebrew-science was deprecated and they won't migrate matplotlib into homebrew-core.

See existing issue #50

@Shongololo ... sounds like an explanation. but ist here somebody who could provide a solution. i think many of those interested in that topic are qgis 3 mac users who desperately look for the latest qgis-release and are not too familiar with homebrew internas ...

@rkalasek just providing some background and pointing to the issue thread where the related discussion is happening. If I have a chance I might tackle the solution I suggested in #50, though I was hoping that some of the existing contributors / maintainers could comment on whether they'd support the suggested direction.

thx for the effort - in the meantime i've installed matplotlib via pip and
tried to edit the formula (outcommented the matplot-statement)
and use this local version ... without beeing successfully.
