我尝试了Python提供的解决方案，但没有看到pygraphviz，但是它不起作用。

python  macos  installation  pip  pygraphviz

sudo apt-get install python-dev graphviz libgraphviz-dev pkg-config

如果您使用的是Python 3，则可能需要执行以下操作：

sudo apt-get install python3-dev graphviz libgraphviz-dev pkg-config

然后

pip install pygraphviz

我发现我需要先做sudo apt-get install python-dev，否则我会得到大约缺少一个编译错误，Python.h在做的时候pip install pygraphviz。

如果有人遇到类似问题，我已经更新了python-dev要求。谢谢。
— Dhiraj Dhule
第一步，您可以指定所需的python版本：例如sudo apt-get install python3.6-dev。默认值为2.7。另外，使用的第二步sudo给了我一个pip导入错误，但是删除它解决了问题并安装了pygraphviz。

请注意。运行“ sudo pip ...”可能不是一个好主意。最好将pip保留为虚拟环境的一部分，如果没有，则只需以常规用户身份运行pip。见stackoverflow.com/questions/21055859/…–

对于MacOS，我需要执行以下操作：

$ brew install graphviz
$ sudo pip install pygraphviz

我使用了virtualenv和Python 3，并且pip install graphviz无需任何其他选项就可以运行，并且工作正常（在之后brew install graphviz）。
— 特伦顿
哦，谢谢。非常感谢。你救了我的一天，我的屁股被踢了。:)

按照@Trenton的说明-pip install graphviz运行后，我发现所有要求都得到满足，brew install graphviz并且brew安装在字体上暂停了很长时间。

在macOS上，我做到了，

$ brew install graphviz
$ sudo pip install pygraphviz

没为我工作。安装graphviz之后，我必须下载pygraphviz的git项目并使用sudo python3 setup.py install --include-path=/usr/local/Cellar/graphviz/2.40.1/include/graphviz --library-path=/usr/local/Cellar/graphviz/2.40.1/lib

对于CentOS。由于需要graphviz-devel来解决此问题，因此您需要使用yum进行安装。为此，您需要在仓库可用的地方添加仓库。以我为例，原子存储库工作正常。

wget -q -O - http://www.atomicorp.com/installers/atomic | sh

这将添加原子仓库，然后

sudo yum install graphviz-devel

而且您应该能够执行 

pip install pygraphviz

在使用python-alpine映像为Django创建Dockerfile时遇到了这个问题。

由于这篇博文添加了“ graphviz-dev”包以及我的应用程序的其他依赖项，因此我能够解决它。

例：

#Install dependencies
RUN apk add --update --no-cache --virtual .build-deps \
    build-base \
    alpine-sdk \
    postgresql-dev \
    libffi-dev \
    python3-dev \
    libffi-dev \
    jpeg-dev \
    zlib-dev \
    musl-dev \
    libpq \
    graphviz-dev \  
    && pip install --no-cache-dir -r /code/requirements_dev.txt \
    && find /usr/local \
        \( -type d -a -name test -o -name tests \) \
        -o \( -type f -a -name '*.pyc' -o -name '*.pyo' \) \
        -exec rm -rf '{}' +

问候
