....
Successfully installed graphviz-0.5.1

$ sudo pip install cgraph
...
Successfully installed cgraph-0.1

我遇到問題No package 'libcgraph' found while running sudo pip install pygraphviz 。 以下是完整的堆棧跟蹤。

我嘗試了Python提供的解決方案沒有看到 pygraphviz ，但它不起作用。

Answer 1

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

或者，如果您使用的是 Python 3，則可能需要以下內容：

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

那么

pip install pygraphviz

Answer 2

對於 MacOS，我需要執行以下操作：

$ brew install graphviz
$ sudo pip install pygraphviz 

Answer 3

對於 Fedora 用戶：

1. yum 列表可用graphviz*
2. 為您的 Fedora 發行版選擇合適的軟件包
3. sudo yum install 'graphviz-devel.x86_64'
4. pip install pygraphviz

Answer 4

在 macOS 上，我做到了，

$ brew install graphviz
$ sudo pip install pygraphviz

Answer 5

對於 CentOS。 由於需要使用 graphviz-devel 來解決此問題，因此您需要使用 yum 安裝它。 為此，您需要在包可用的地方添加 repo。 就我而言， Atomic repos 工作正常。

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

這將添加原子回購，然后

sudo yum install graphviz-devel

你應該能夠執行

pip install pygraphviz

Answer 6

我在使用 python-alpine 圖像為 Django 創建 Dockerfile 時遇到了這個問題。

由於這篇文章添加了包“graphviz-dev”以及我的應用程序的其余依賴項，我能夠解決它。

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 '{}' +
