graphviz não instala no Mac

Estou fazendo a aula de visualização das decisões de um estimador rodando notebook local. Eu já consegui instalar o graphviz via brew, mas a instalação pelo pip não funciona de jeito nenhum.

O Comando que estou tentando rodar:

!pip3 install --trusted-host pypi.org pygraphviz

A resposta que estou tendo: ​

Já tentei algumas versões do graphviz como 0.10 (demonstrado na aula) e mais recente como 0.14 e o resultado foi igual.

Versão do Python: 3.7.3

Versão do pip: 20.1

Pesquisei um pouco sobre e as soluções envolvem reinstalar o python, reinstalar o pip e não me parece que funcionaria.

Alguém já teve esse problema?

PS: nesse exemplo eu estava usando o pygraphviz, que foi uma das soluções que encontrei. Também tentei python-graphviz e o graphviz mesmo. Todos deram o mesmo problema
