我在 macOS 10.10.5 上安装 pygraphviz 时遇到问题。我安装了功能齐全的 Python 2.7.x，并且我想运行 queing-tool 的测试示例，这需要 使用 pip 安装 pygraphviz。
执行命令
pip install pygraphvizCollecting pygraphviz

我不确定如何解决上述错误。所有其他 Python 包（例如 numpy 或 networkx）都易于安装。任何帮助将不胜感激。提前非常感谢。
试试这个：
sudo apt-get install python-dev graphviz libgraphviz-dev pkg-config
或者如果您使用的是 Python 3，可能需要以下内容：
sudo apt-get install python3-dev graphviz libgraphviz-dev pkg-config
然后
sudo pip install pygraphviz
这对我有用（M1 Mac）
brew install graphviz
python -m pip install \
--global-option=build_ext \
--global-option="-I$(brew --prefix graphviz)/include/" \
--global-option="-L$(brew --prefix graphviz)/lib/" \
pygraphviz
这为我解决了这个问题：
python3 -m pip install -U --no-cache-dir \
--config-settings="--global-option=build_ext" \
--config-settings="--global-option=-I$(brew --prefix graphviz)/include/" \
--config-settings="--global-option=-L$(brew --prefix graphviz)/lib/" \
pygraphviz
感谢这个 GitHub 回复，我只添加了 -U 和 --no-cache-dir 标志。
基本上你需要先使用brew下载
graphvizbrew install graphviz
pip install graphviz
pip install pygraphviz
您也可以尝试使用
pip3pip安德鲁的评论让我走上了正确的道路。谢谢你。
事实证明，stackoverflow 上已经提供了在 macOS 上安装 pygraphviz 的详细解决方案，请参阅 teut 的解决方案。
