GLib-GObject-CRITICAL **: gtype.c:2720: You forgot to call g_type_init()

[tdhulster]

I installed WeasyPrint and all packages that were listed in the Weasyprint - documentation

I'm using Mac OS X 10.8.2
and Python 2.7
And installed Weasyprint in my virtualenv .

Now when i try :
HTML('http://weasyprint.org/').write_pdf('/tmp/weasyprint-website.pdf')

I get following message in my console :

I googled the GLib-GObject-CRITICAL but didn't find a solution, does anyone knows how to fix this?

Hi,

Thanks for reporting this. I can’t reproduce this on Linux, and don’t have a Mac to test. What happens afterwards? Does Python crash? Do you get a traceback? Do you get a PDF file?

In any case, I just pushed a change to master to add a call to gobject.g_type_init(). Can you try the git version and see if it fixes the issue? This should work:

pip install git+git://github.com/Kozea/WeasyPrint.git

[tdhulster]

I tried the git version out and still get the same error ...
No crash, no traceback no pdf ...

Hello, Is it the same error or I just installed something wrong?
Windows 7. Python 2.7.

pygtk-all-in-one-2.24.0.win32-py2.7.msi
CFFI and lxml from http://www.lfd.uci.edu/~gohlke/pythonlibs/

[SimonSapin]

My mistake. @migrome , can you try again with the change I just pushed to master? @tdhulster , if you did not have the same AttributeError @migrome , I suspect you might not be using the git version.

[migrome]

Works fine, thank you.

[tdhulster]

I did this :
pip install git+git://github.com/Kozea/WeasyPrint.git

But do I have to do something more to use it or should that work?

[SimonSapin]

@tdhulster do you still have the error with the latest master now? Sometimes pip does nothing when it thinks everything is already installed. Does the output ends with something like "Installed WeasyPrint"? If not, try pip install --upgrade --no-deps (Just --upgrade would also reinstall all dependencies recursively.)

[SimonSapin]

@tdhulster, I believe this bug is fixed now. Can you confirm? (Make sure you’re using the latest master, see previous message.)

[SimonSapin]

Closing for lack of response plus belief that this is fixed.

[barathik]

I am getting the same error in mac. Was this resolved?

[majidhosseini]

I am getting the same error on Arch Linux, and I used the last version (42.03).
