pip install pygraphviz: No package 'libcgraph' found

Question

I succeed in installing graphviz and cgraph with

$ sudo pip install graphviz
....
Successfully installed graphviz-0.5.1

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

I encounter the issue No package 'libcgraph' found while running sudo pip install pygraphviz. Below is the full stacktrace.

$ sudo pip install pygraphviz

Answer 3

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

or the following might be needed if you’re using Python 3:

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

then

pip install pygraphviz

Answer 4

For CentOS.
As graphviz-devel is required to fix this issue, you will need to install it with yum. To do this you are required to add repo’s where package is available. In my case Atomic repos worked fine.

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

This will add atomic repos, then

sudo yum install graphviz-devel

And you should be able to perform

pip install pygraphviz

Answer 6

I ran into this problem when creating a Dockerfile for Django with a python-alpine image.

I was able to solve it thanks to this post adding the package "graphviz-dev" along with the rest of my app’s dependencies.

Example:

#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 '{}' +
