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

I tried the solutions provided by Python does not see pygraphviz, but it doesn't work.

Solution 1

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

Solution 2

For MacOS, I needed to do:

$ brew install graphviz
$ sudo pip install pygraphviz 

Solution 3

For fedora users:

1. yum list available graphviz*
2. select the appropriate package for your Fedora distribution
3. sudo yum install 'graphviz-devel.x86_64'
4. pip install pygraphviz

Solution 4

On macOS, I made it with,

$ brew install graphviz
$ sudo pip install pygraphviz

Solution 5

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

I found I needed to first do sudo apt-get install python-dev, otherwise I'd get a compile error about a missing Python.h when doing the pip install pygraphviz.

[Dhiraj Dhule]

I have updated the python-dev requirement in case somebody has similar problem. Thanks.

[Trenton]

I was using an virtualenv and Python 3 and I was able to do pip install graphviz without any additional options and it worked fine (after brew install graphviz).

[Jyotirmay]

Oh maann.. Thankx a lot.. This works perfectly for me. You saved my day and my ass being kicked off. :)

[Rob]

As per @Trenton's note--I found all requirements satisfied on pip install graphviz after I had run brew install graphviz note the brew install pauses a long time on font stuff.

[Itay]

Didn't work for me. After installing graphviz, I had to download the git project of pygraphviz and use sudo python3 setup.py install --include-path=/usr/local/Cellar/graphviz/2.40.1/include/gra‌​phviz --library-path=/usr/local/Cellar/graphviz/2.40.1/lib

[Jersey_Guy]

I followed this path for CentOS and was successful.

In the first step, you can specify the python version you want: e.g. sudo apt-get install python3.6-dev. The default is 2.7. Also, for the second step using sudo gave me a pip import error, but dropping it fixed the issue and pygraphviz installed.

[Harlin]

Just a quick note. It may not be a good idea to run "sudo pip ...". It's best to keep pip as part of a virtual environment but if not, then just run pip as your regular user. See stackoverflow.com/questions/21055859/…

[Chesco Igual]

I actually followed this one, but I see it's pretty similar to yours! Thanks github.com/pygraphviz/pygraphviz/issues/86

[Skippy le Grand Gourou]

graphviz itself doesn’t seem to be necessary.

[Skippy le Grand Gourou]

@myself Well, it actually is, despite the absence of explicit dependency.

[Jakob Guldberg Aaes]

Don't do sudo pip! Instead, use pip install --user as there is no reason to install it in the system distro. You risk ending up in an erroneous state.
