2.10.4 installation / FATAL - Cant install CairoSVG

I could install 2.10.4 a few weeks ago on my prod server. PnCevennes got an error when trying to install it yesterday. So I tried to install it on my test server and got the same error.

Install Geotrek python dependencies...
Could not setup python environment !

install.log ends with :

TypeError: 'encoding' is an invalid keyword argument for this function
An error occurred when trying to install CairoSVG 2.0.0rc2. Look above this message for any errors that were output by easy_install.
While:
  Installing django.
  Getting distribution for 'CairoSVG>=0.4.1'.
Error: Couldn't install: CairoSVG 2.0.0rc2

@amandine-sahl could make it work by replacing

eggs/WeasyPrint-0.23-py2.7.egg/EGG-INFO/requires.txt:5:CairoSVG==1.0.20

by

eggs/WeasyPrint-0.23-py2.7.egg/EGG-INFO/requires.txt:5:CairoSVG>=0.4.1

But not sure it is a clean solution.
