Weasyprint fails on Windows 7/Python 2.7.x

[ChameleonRed]

Python 2.7.x
GTK+ Ash (last version)

Why cairo2 not want to load?

$weasyprint

I did need to add the path to GTK installation before running weasyprint.

Have you tried run it like this?

@set PATH=C:\path_to_your_installation\lib;%PATH%
weasyprint

[ChameleonRed]

I added GTK path and not works - GTK explained in documentation. I can try it with different version of GTK - I am using currently Python 2.7 - maybe I need to use Python 3. It takes some weeks until will be time to do it.

@jbouclier @ChameleonRed I've written a small list of instructions to make WeasyPrint work on Windows. Could you try it?

@ChameleonRed

I'm using Python 2.7.11 (64bits) for windows together with GTK2 (64bits) I downloaded from here:

https://github.com/tschoonj/GTK-for-Windows-Runtime-Environment-Installer

May be there are some other dependencies on native libraries, like the C++ compiler @liZe mentions. Is hard for me to tell. I did the installation in a development machine. I lost track what I installed there and why.

[liZe]

When trying to install random GTK versions (for example mixing 64 bit Python with 32 bit GTK), I've met this error, but it works with the new instructions. I close the bug for now, @ChameleonRed feel free to re-open it if needed.

I am also getting same error in my window 8 python 2.7.13.
I uninstalled flask_weasyprint and again installed but isuue not resolved.

@cmaliwal Reinstalling flask_weasyprint is not enough. You can uninstall and reinstall Python and GTK carefully following the steps described in the documentation.

@ChameleonRed This might help you,

sudo apt-get install libcairo2 libpango1.0-0
