Failing to install python-igraph - linux

Question

I'm trying to install python-igraph. After I run sudo pip install python-igraph I got the following log:
Downloading/unpacking python-igraph
Downloading python-igraph-0.7.1-1.tar.gz (375kB): 375kB downloaded
Running setup.py egg_info for package python-igraph

Cannot find the C core of igraph on this system using pkg-config.
We will now try to download and compile the C core from scratch.
Version number of the C core: 0.7.1-1
Version 0.7.1-1 of the C core of igraph is not found among the nightly builds.
Use the --c-core-version switch to try a different version.
Could not download and compile the C core of igraph.
WARNING: we were not able to detect where igraph is installed on
your machine (if it is installed at all). We will use the fallback
library and include pathss hardcoded in setup.py and hope that the
C core of igraph is installed there.
If the compilation fails and you are sure that igraph is installed
on your machine, adjust the following two variables in setup.py
accordingly and try again:

And I have similar situation if I do it with sudo python setup.py install.
Apparently the problem is with C core.
How can I install the correct version of it so that I can install igraph?
I use Linux Mint 16 64-bit, python 2.7.

Answer 1

You need igraph libraries before compiling python-igraph.
Try sudo apt-get install -y libigraph0-dev and try install python-igraph again.

Answer 2

Using Ubuntu 16 and Python3.
pip3 install python-igraph
results in error building whell. However,
sudo apt-get install python3-igraph
worked just fine.

Answer 3

For windows users
Download the unofficial python-igraph (according to igraph official installation instruction), please select the appropriate .whl file based on environment (python version, 64bit vs. 32bit).
Open command console and cd into .whl's folder
Execute the following command:
pip install python_igraph-0.7.1.post.xxx.whl

Answer 4

In ubuntu 16.04:
For python 2:
apt-get install build-essential python-dev libxml2 libxml2-dev zlib1g-dev
For python 3:
apt-get install build-essential python3-dev libxml2 libxml2-dev zlib1g-dev
Solved my problem.

Answer 5

For Ubuntu Users :
Add the repository of igraph to apt:
sudo add-apt-repository ppa:igraph/ppa
Then update and install the python-igraph package:
sudo apt-get update
sudo apt-get install python-igraph
