Setup using pip broken since CairoSVG dropped Python 2 support #394
Problem seems to be in METADATA file which contains dependency on cairosvg >= 1.0.20. This automatically downloads CairoSVG 2.0 and so it fails.
I've seen that there is already a patch solving this problem in setup.py, which should limit the CairoSVG version to 1.0.20 but somehow it is not applied in package in PyPI. I would suggest that the package was built in Python 3 environment and so the extra dependency was therefore skipped. However I am not an expert on Python packaging so I am not sure if such a scenario is even possible.
The workaround to make things working is to set CairoSVG==1.0.20 in your requirements.txt file (or whenever you store packages your projects) which should effectively freeze it.
The text was updated successfully, but these errors were encountered:
I am experiencing problems with installing WeasyPrint 0.32 into my python 2.7.12 virtualenv using pip. It is caused by new release of CairoSVG (2.0), which setup fails cause it no longer supports Python 2.
Which version are you updating from? I experienced the same problem and solve it by upgrading step by step, from 0.29 to 0.30 and so on. Andreas…
