我尝试了Python does not see pygraphviz提供的解决方案，但它不起作用。

Answer 1

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

然后

sudo pip install pygraphviz

Answer 2

对于MacOS，我需要这样做：

$ brew install graphviz
$ sudo pip install pygraphviz

Answer 3

对于fedora用户：

可用的yum列表graphviz*
为您的Fedora发行版选择适当的包
sudo yum install 'graphviz-devel.x86_64'
pip install pygraphviz

Answer 4

在macOS上，我用它做了，

$ brew install graphviz
$ sudo pip install pygraphviz

Answer 5

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，您需要添加包可用的repo。在我的情况下，Atomic回购工作正常。

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

这将添加原子回购，然后

sudo yum install graphviz-devel

你应该能够执行

pip install pygraphviz

Answer 6

为带有python-alpine映像的Django创建Dockerfile时遇到了这个问题。

由于这篇文章添加了程序包“ graphviz-dev”以及我的应用程序的其他依赖项，因此我得以解决。

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 '{}' +
