Q:

OSError importing python-igraph

I am trying to import igraph but it keeps throwing this error at me:
>>> import igraph

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/site-packages/igraph/__init__.py", 
line 36, in <module>

    cairo = dlopen(ffi, 'cairo', 'cairo-2')
  File "/usr/local/lib/python3.6/site-packages/cairocffi/__init__.py", 
 line 38, in dlopen
    raise OSError("dlopen() failed to load a library: %s" % ' / 
'.join(names))
OSError: dlopen() failed to load a library: cairo / cairo-2

I have tried to follow this guide to install cairo but it throws this error and doesn't solve the igraph import issue: error: mandatory image surface backend feature could not be enabled
I have also tried to install pycairo but that resulted in no module founds: cairo, which brought me back to square one.
I tried running sudo port install cairo as per https://cairographics.org/download/ instructions. But that results in Error: Port cairo not found

My sys config:

MacOS High Sierra 10.13.1 
Python 3.6
python-igraph 0.7.1

I am clueless as to what can be the issue. Any help would be highly appreciated. Thank you :)

A:

Thanks to @Aiven I have managed to solve my issue. If anyone ever comes across the same problem, this have done the trick for me:
brew install cairo
brew install py2cairo
brew install igraph  (install C-core)
sudo pip install python-igraph (install igraph for python)
