我尝试了Python does not see pygraphviz提供的解决方案，但没有用。

Answer 1

在 macOS 上，我使用

$ brew install graphviz
$ sudo pip install pygraphviz

Answer 2

Fedora 用户：

yum 列表可用 graphviz*
select 适合您的 Fedora 发行版的软件包
sudo yum install 'graphviz-devel.x86_64'
pip install pygraphviz

Answer 3

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

或者如果您使用的是 Python 3:

，则可能需要以下内容

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

然后

pip install pygraphviz

Answer 4

对于 CentOS。由于需要 graphviz-devel 来解决此问题，因此您需要使用 yum 安装它。为此，您需要在包可用的地方添加回购协议。在我的例子中 Atomic 回购工作正常。

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

这将添加原子存储库，然后

sudo yum install graphviz-devel

而且您应该能够执行

pip install pygraphviz

Answer 5

对于 MacOS，我需要做：

$ brew install graphviz
$ sudo pip install pygraphviz

Answer 6

我运行在使用 python-alpine 图像为 Django 创建 Dockerfile 时遇到了这个问题。

多亏了这个 post 添加包“graphviz-dev”以及我的应用程序的其余依赖项，我才能够解决它。

示例：

#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 '{}' +
