Czy ktoś może doradzić? Dzięki

Answer 1

byłem coraz ten sam błąd i był w stanie go rozwiązać instalując libfreetype6-dev i libpng12-dev.

sudo apt-get install libfreetype6-dev libpng12-dev

Dzięki @koukouviou za wskazanie upstream raport o błędzie, co znacznie przyspieszyło proces Znalezienie rozwiązania.

Answer 2

Jest zamknięty issue w github tracker matplotlib do tego. To nie jest problem z matplotlib, ale z innymi pakietami (freetype i png są wymienione w dyskusji).

Według dyskusji komunikat o błędzie jest bardziej opisowy w gałęzi głównej:

• The following required packages can not be built: * freetype, png
