TypeError: can't multiply sequence by non-int of type 'float'

[dosena]

This exception crept in after upgrading from version 0.19.2 to 0.20.0 (and is still present in 0.21.2)

The line in question (preferred.py:170):
return width.value / 100. * table.width

In my case, table.width is 'auto'.

Adding an additional check table.width != 'auto' on line 169 and on line 156 fixes the problem.

Hi. Thank you for reporting this. It looks like a duplicate of #152. Does upgrading to master fix it? If so I’ll make a PyPI release. To upgrade:

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

… or maybe this, as we haven’t bumped the version number yet:

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

Yes, upgrading to master fixes it.

Version 0.21 is on PyPI and fixes this.
